# sign
fun sign(message: ByteArray, timestamp: Date, user: User, pinProvider: PinProvider, resultHandler: ResultHandler<Signature, SigningException>)
Create a cryptographic signature of the given document.
# Parameters
| message | the hash of the given document. |
| timestamp | when the document is signed. |
| user | an user with already registered signing identity. |
| pinProvider | a callback called from the SDK, when the signing identity PIN is required. |
| resultHandler | a callback to handle the result of the signing. - If successful, the result is MIRACLSuccess. - If an error occurs, the result is MIRACLError with a message. On exception, the exception object is also passed. |
