libsodium.PKI.SignData

libsodium.PKI.SignData

Method Signature

 Protected Function SignData(Message As MemoryBlock, SenderKey As libsodium.PKI.SigningKey, Detached As Boolean = False, Exportable As Boolean = False) As MemoryBlock

Parameters

Name	Type	Comment
Message	MemoryBlock	The data to be signed.
SenderKey	SigningKey	The signer's key pair.
Detached	Boolean	Optional. if True then only the signature is returned. The default is False which returns the Message and the signature concatenated.
Exportable	Boolean	Optional. If True then the return value is encoded in a text-based export format; otherwise the raw binary data is returned.

Return value

The Message and signature concatenated, or (if Detatched=True) the signature only. On error returns Nil.

Remarks

Digitally signs the Message using the private half of the specified Ed25519 key pair. By default, the message and signature are returned concatenated. To get the signature only specify the Detatched parameter.

If Exportable=True then the return value is the signed message encoded in a plain text format. Both the raw binary and plain text format are understood by the VerifyData method.
