NewEnvelopeSigner creates an EnvelopeSigner that uses 1+ Signer algorithms to sign the data.

NewMultiEnvelopeSigner creates an EnvelopeSigner that uses 1+ Signer algorithms to sign the data.

PAE implementes the DSSE Pre-Authentic Encoding https://github.com/secure-systems-lab/dsse/blob/master/protocol.md#signature-definition */.

ErrNoSignature indicates that an envelope did not contain any signatures.

ErrNoSigners indicates that no signer was provided.

Envelope captures an envelope as described by the DSSE specification.

EnvelopeSigner creates signed Envelopes.

Signature represents a generic in-toto signature that contains the identifier of the key which was used to create the signature.

Signer defines the interface for an abstract signing algorithm.

SignerVerifier provides both the signing and verification interface.

Verifier verifies a complete message against a signature and key.

Deprecated: switch to renamed SignerVerifier.
