certificate string HEX string for the PEM encoded certificate
publicKey module:api.Key The public key represented by the certificate
mspId string The associated MSP's ID that manages this identity
cryptoSuite module:api.CryptoSuite The underlying CryptoSuite implementation for the digital signature algorithm
signer Signer The signer object encapsulating the opaque private key and the corresponding digital signature algorithm to be used for signing operations
