Provides support for building RSASSA-PKCS1-v1_5 signature contexts. This class derives SignatureContextBuilder providing the same methods but internally using a specific signature scheme.

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

Inherited from

SignatureContextBuilder.digestAlgorithm

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

Inherited from

SignatureContextBuilder.signingAlgorithm

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.

Inherited from

SignatureContextBuilder.buildSigningContext

buildVerificationContext()

buildVerificationContext(key): VerificationContext Build a context for verification operations. This context can be used to verify digital signatures using the specified public key.

Parameters

key
PublicKey The public key to use for verification.

Returns

VerificationContext A verification context object.

Throws

AccessDeniedError If the key lacks the KeyPurpose.VERIFY purpose.

Throws

InvalidArgumentError If the signing algorithm is not supported.
