Instance Method Details

#generate_token_signature(token_bytes, private_key) ⇒ Object

Generates the digital signature for the specified token_bytes

using the specified [VirgilPrivateKey]

for which to compute the signature. bytes of access token.

Parameters:

  • token_bytes (Bytes) —

    The material representation bytes of access token

  • private_key (VirgilPrivateKey) —

    The digital signature for the material representation

Returns:

  • The digital signature for the material representation bytes of access token.

end

#verify_token_signature(signature, token_bytes, public_key) ⇒ Boolean

Verifies that a digital signature is valid by checking the signature, provided public_key and token_bytes for which the signature has been generated. key for verification.

Parameters:

  • signature (Bytes) —

    The digital signature for the token_bytes

  • token_bytes (Bytes) —

    The material representation bytes of access token

  • public_key (VirgilPublicKey) —

    public

Returns:

  • (Boolean) —

    True if signature is valid, False otherwise.
