Sign & verify data with a Cardano Secret/Public-Key
Sign & verify CIP-8, CIP-30 & CIP-36 data (Catalyst)
Generate Cardano-Keys from (Hardware)-Mnemonics and Derivation-Paths
Canonize, Hash & Sign Governance Metadata CIP-100/108/119
Â
- Sign any hexdata, textdata or binaryfile with a provided normal or extended secret key. The key can be provided in hex, bech or file format. The signing output is a signature in hex- or json-format, also the public key of the provided secret key for verification. With the enabled
--jcliflag the generated signature and public key will be return in a jcli compatible bech format. Cardano-signer can be used instead of jcli for signing. - Sign payloads in CIP-8 / CIP-30 mode, hashed or not hashed, with or without a payload in the output. The signing output is a COSE_Sign1 signature in hex format and also the public key of the provided secret key for verification. The output can also be set to be in json format which will also show additional data (--json-extended).
- Generate and sign Catalyst registration/delegation/deregistration metadata in CIP-36 mode. This also includes relatively weighted voting power delegation. The output is the registration/delegation or deregistraton data in json or cborHex-format and/or a binary cbor file, which can be transmitted on chain as it is.
- Generate Cardano Keys like .skey/.vkey files and hex-keys from derivation paths, with or without mnemonic words.
- Support for Hardware-Wallet derivation types Ledger & Trezor.
- Generate conway dRep Keys, Constitutional Commitee Member Cold/Hot Keys with or without mnemonic words.
- Canonized & Hash CIP-100/108/119 governance metadata jsonld data
- Sign CIP-100/108/119 governacne metadata by adding an authors signature to the document
- Generate CIP-36 voting-keys.
- A given address will automatically be checked against the used publicKey.
- Verify a signature for any hexdata, textdata or binaryfile together with a provided public key. Also an optional address can be verified against the given public key. The key can be provided in hex, bech or file format. The verification output is true(exitcode=0) or false(exitcode=1) as a console output or in json-format.
- The signature can be provided in hex format or also in bech encoded
ed25519_sigformat. Cardano-signer can be used instead of jcli for verification. - Verify CIP-8 / CIP-30 COSE_Sign1/COSE_Key data. With hashed or non-hashed payloads. There is also a detailed check on the COSE_Sign1 and COSE_Key data structure included. Verification can be done on the COSE_Sign1 + COSE_Key, or COSE_Sign1 + COSE_Key + payload and/or address.
- Verify CIP-100/108/119 metadata JSONLD files

To verify the COSE data with a detailed output run:
cardano-signer verify --cip8 \

}You see that the verification was successful, the used signing-address, and payload was not hashed.
If you wanna verify the COSE data against a given payload, simply add it as a --data parameter:
cardano-signer verify --cip8 \
--cose-sign1 84582aa201276761646472657373581d617863b5c43bdf0a06608abc82f0573a549714ff69166074dcdde393d8a166686173686564f44b48656c6c6f20776f726c645840fc58155f0cee05bc00e7299af1df1f159ac82a46a055786b259657934eff346eec81349d4678ceabc79f213c66a2bdbfd4ea5d9ebdc630bee5ac9cce75cfc001 \

--data 'Not hello world' \
--json{
"result": "false"
}If you have a COSE_Sign1 without an included payload (like the signing example further above), you need to provide the payload data to do a successful verification. In the example the payload was 'Hello world' but was not included in the COSE_Sign1, so we add it.

}As you can see, this generates a new keypair with random mnemonics for the given derivation path 1852H/1815H/0H/0/0. You can also use the format "1852'/1815'/0'/0/0" for the path, just make sure you put the whole path in doublequotes.
This generated mnemonics are in the Shelley(Icarus) standard BIP39 format and will work with all major wallets like Eternl, Typhoon, etc.
Also a Xpub... key was generated, which can be used to view wallet data in external tracking apps.
Like with the normal ed25519 keys, use the --out-skey & --out-vkey parameters to directly write out .skey/.vkey files.

}Providing the --cip36 flag sets the parameters to generate CIP36 conform voting key.
You can achieve the same result by setting --path 1694H/1815H/0H/0/0 or using the shortcut --path cip36.
Like with the examples before, you can write out .skey/.vkey files if needed.
Such a generated voting key can be used to be included in the CIP36(Catalyst) registration metadata, which can also be generated & signed by cardano-signer. You can delegate Voting-Power to such a voting key. Later on you can restore a Wallet in a dApp enabled LightWallet like Eternl with the generated mnemonics to do the Voting via the VotingCenter.

}As you can see, the path is recognized as a CC-Hot Signing/Verification key path.
You can achieve the same result by setting --path 1852H/1815H/0H/5/0.
Like with the examples before, you can directly also write out .skey/.vkey files if needed.
If you wanna use your own mnemonics, just provide them via the --mnemonics parameter!

}Cardano-Signer is doing the following steps to sign the document:
- check that the provided input data is a valid JSON file
- canonize the
@contextandbodypart via URDNA2015 method and hash it via black2b-256 method - check that the
hashAlgorithmisblack2b-256 - check any preexisting
authorsarray entry to be valid - check that there is no duplicated public-key entry
- sign the canonized hash with the provided secret-key and author-name
Additional authors can be added by simply running the same command multiple times!
Also, if you write out the new file directly via the --out-file parameter, the output of cardano-signer becomes a json with the basic infos of the new file, including the anchorHash. Ready do be used with governance on Cardano.
{
"workMode": "sign-cip100",
"outFile": "CIP108-example-signed.json",

}
As we already learned, you can use cardano-signer to sign a governance metadata file with author signatures. This function is doing the verification of such documents.
Lets use the same document that we generated above:
cardano-signer verify --cip100 \
--data-file CIP108-example-signed.json \
--json-extendedThis gives us the following result:

}If you're interested in the raw canonized data, that can be written out to an extra file using the --out-canonized parameter like:
cardano-signer canonize --cip100 \
--data-file CIP108-example.json \
--out-canonized CIP108-example.canonized \
--json-extendedAnd of course you can write out the plaintext or json output also directly to a file like with the other functions. This is simply done by using the --out-file parameter.

1.20.0
- Two new flags have been added to the
keygenmode:--ledgerlet you derive your keys in Ledger-Hardware-Wallet type format--trezorlet you derive your keys in Trezor-Hardware-Wallet type format
This new function allows to recover keys from a Hardware-Wallet as pure CLI-Keys.
- The preset path
--path poolhas been added to thekeygenmode, to directly derive Cardano-Pool Cold-Keys - The
pathentry in the--json-extendedoutput for thekeygenmode was renamed intoderivationPath(breaking!) - A new entry was added in the
--json-extendedoutput for thekeygenmode ->derivationType, which can beicarus,ledgerortrezor - If keys are derived for
--path drepor--path pool, the output now also contains the corresponding DRep-ID/Pool-ID.
- Two new flags have been added to the
-
1.19.0
- A new function is now available via the 'sign --cip100' parameter. Its now possible to add authors entries (Name + Signature) with a single command using cardano-signer
- cardano-signer is now compatible with CIP129 standard for drep, committee-cold and committee-hot bech strings. this works now for all functions that allow a '--address' parameter.
- CIP 8/30 DataSign:
- you can now directly also use governance bech-ids for the '--address' parameter like 'drep1xxx'
- CIP 100 - Governance:
- the canonize&hash command 'hash' introduced in version 1.17 was renamed to 'canonize'. change was made to avoid confusion, because this command is to output the hash of the canonized body, not the file-hash.
- output fields of the 'canonize' and 'verify' function changed 'hash' is now 'canonizedHash', 'canonized' is now 'canonizedBody'
- in addition to the existing checks in the 'verify' function, cardano-signer now also checks for duplicated public-key entries in the authors array of the input jsonld file

-
1.16.0
- Added a new flag
--nohashcheckfor the signing and verification in CIP030/008 format. Using this flag will tell cardano-signer to not perform a check of the hash in the address-field against the public-key during the verification process. And additionally it can disable the address/hash check in the signing process too.

--path payment,--path stake,--path cip36
-
1.12.1
- Changed the
--rewards-addressparameter to--payment-addressparameter. This reflects the latest changes in CIP-36 - Also the keys for
rewardsAddressHex,rewardsAddressTypeandrewardsAddressNetworkin the--json-extendedoutput are not renamed topaymentAddressHex,paymentAddressType,paymentAddressNetwork
- Changed the
-
1.12.0
- The output via
--json-extendedis now showing more details about the address (hex, type, network) - The help description can now be displayed for each sub command like:
cardano-signer sign --cip8 --help - Addresses provided via the
--addressparameter can now be a bech-address, hex-string or the path to a file containing the bech-address (typical mywallet.addr) files
- Completely reworked CIP-8/CIP-30 code. Flags
--cip8&--cip30will currently do the same, because CIP-30 uses CIP-8 signing. - Signing a payload now generates a full COSE_Sign1 signature together with the COSE_Key publicKey
- The payload can be set to hashed via the new flag
--hashed - The payload can be excluded from the COSE_Sign1 signature with the new flag
--nopayload - The signing address will be automatically checked against the publicKey (signing and verification)
- Extended data structure check of the given COSE_Sign1 & COSE_Key

--addressparameter. If provided, cardano-signer checks that the address belongs to the provided signing/public key.
- Added an optional address check for the normal sign/verify functions via the
-
1.9.0
- Added the new deregistration metadata format in CIP-36 mode, which is using key 61286 for the deregistration data.
- Changed the output of
--json-extendedin CIP-36 mode to output the cbor and json content below the "output" key example
- Using the general bech32 lib to decode public/private keys, so any bech32 string can be used. Before it was limited to
ed25519_pkanded25519_skprefixes. - Defining command-line argument types to avoid parsing arguments like
--data-hex="000000"as a number. Must be parsed as a string of course. - Added command-line aliases so you can also use:
--signing-keyor--secret-key,--verification-keyor--public-key, etc.
-
1.8.0
- Allow duplicated voting_key entries
- New check to avoid using a wrong vote-public-key or a wrong stake secret-key. Because the public-key of the signing secret-key must be different than the entries in the delegations array.
- New check that the total-vote-weight is not zero
- Added the fields
votePurposeandtotalVoteWeightto the--json-extendedoutput-mode - Syntax Update: Added flag
--deregisterto generate an empty delegation array, no voting_keys or rewards address is needed using that flag - Syntax Update: If no
--nonceparameter is provided, cardano-signer automatically calculates the Mainnet slotHeight from the current machine time and uses it as the nonce
- Syntax Update: Added parameter
--testnet-magic [xxx]to CIP-8 and CIP-36 mode to allow an additional check about the right bech-address format. (Default = mainnet)
-
1.7.0
- Added JSON and JSON-Extended output format: Default output format is plaintext, using the
--jsonflag generates a JSON output. Using the--json-extendedflag generates a JSON output with much more information. - In CIP-36 mode, using the new
--jsonflag together with the--out-fileparameter generates directly a JSON Format which is compatible to be used as a registration.json metadata with cardano-cli.--out-cboralways generates a binary registration.cbor metadata file, also compatible to be used with cardano-cli. - Usage/Help context is now colored for better readability
- Added JSON and JSON-Extended output format: Default output format is plaintext, using the
-
1.6.1
- Added new check in CIP-36 mode to avoid duplicated voting_key entries in the delegations. Exits with an error if duplicates are found.
-
1.6.0
