Accessors

​

digestAlgorithm

​

Set Signature

set digestAlgorithm(algorithm): void Set the digest algorithm to use for hashing message contents. This will default to SHA-256 if not specified.

Throws

InvalidArgumentError If the algorithm is invalid.

Parameters

algorithm

DigestAlgorithm The digest algorithm to use.

Returns

void

​

signingAlgorithm

​

Set Signature

set signingAlgorithm(algorithm): void Set the algorithm to use for signing. If not specified, this will be determined from the key type if possible.

Throws

InvalidArgumentError If the algorithm is invalid.

Parameters

algorithm

AsymmetricAlgorithm The asymmetric algorithm to use for signing.

Returns

void

​

Methods

​

buildSigningContext()

buildSigningContext(key): SigningContext Build a context for signing operations. This context can be used to create digital signatures using the specified private key.

​

Parameters

key

PrivateKey The private key to use for signing.

​

Returns

SigningContext A signing context object.

​

Throws

AccessDeniedError If the key lacks the KeyPurpose.SIGN purpose.

​

Throws

InvalidArgumentError If the signing algorithm is not supported.
