ISignatureContextBuilder

​

Interface ISignatureContextBuilder

interface ISignatureContextBuilder

Extends com.amazon.apmf.IStandard Interface for building signature contexts.

​

Methods

​

signingAlgorithm()

ISignatureContextBuilder* signingAlgorithm(IAsymmetricAlgorithm* alg)

Set the algorithm to use for signing. If not specified, this will be determined from the key type if possible.

​

Parameters

alg

IAsymmetricAlgorithm* — Required The asymmetric algorithm to use for signing.

​

Returns

ISignatureContextBuilder* The signature context builder object.

---

​

digestAlgorithm()

ISignatureContextBuilder* digestAlgorithm(IDigestAlgorithm* alg)

Set the digest to use for hashing message contents. This will default to SHA256 if not specified.

​

Parameters

alg

IDigestAlgorithm* — Required The digest algorithm to use.

​

Returns

ISignatureContextBuilder* The signature context builder object.

---

​

buildSigningContext()

ISigningContext* buildSigningContext(IPrivateKey* key)

Build a context for signing operations.

​

Parameters

key

IPrivateKey* — Required The private key to use for signing.

​

Returns

ISigningContext* The signing context object.

---

​

buildVerificationContext()

IVerificationContext* buildVerificationContext(IPublicKey* key)

Build a context for verification operations.

​

Parameters

key

IPublicKey* — Required The public key to use for verification.

​

Returns

IVerificationContext* The verification context object.
