Method Signatures

 Protected Function VerifyData(SignedMessage As MemoryBlock, SignerPublicKey As libsodium.PKI.PublicKey) As MemoryBlock
 Protected Function VerifyData(SignedMessage As MemoryBlock, SignerPublicKey As libsodium.PKI.PublicKey, DetachedSignature As MemoryBlock) As Boolean
 Protected Function VerifyData(SignedMessage As Readable, SignerPublicKey As libsodium.PKI.PublicKey, Signature As MemoryBlock) As Boolean
 Protected Function VerifyData(Algorithm As libsodium.HashType, SignedMessage As Readable, SignerPublicKey As libsodium.PKI.PublicKey, Signature As MemoryBlock) As Boolean

Parameters

VerifyData(MemoryBlock, PublicKey) As MemoryBlock

Name	Type	Comment
SignedMessage	MemoryBlock	The data, with attached signature, to be verified.
SignerPublicKey	PublicKey	The public half of the signer's key pair.

VerifyData(MemoryBlock, PublicKey, MemoryBlock) As Boolean

Name	Type	Comment
SignedMessage	MemoryBlock	The data to be verified.
SignerPublicKey	PublicKey	The public half of the signer's key pair.
DetachedSignature	MemoryBlock	The detached signature.

VerifyData(Algorithm As libsodium.HashType, Readable, libsodium.PKI.PublicKey, Signature As MemoryBlock) As Boolean

Name	Type	Comment
Algorithm	HashType	Optional. If specified, the type of generic hash to use.
SignedMessage	Readable	The data to be verified.
SignerPublicKey	PublicKey	The public half of the signer's key pair.
Signature	MemoryBlock	The signature to be verified.

Return value

For detached signatures this method returns True if the signature is valid, and False otherwise.

For concatenated signatures this method returns the message without the signature if the signature is valid, and Nil otherwise.

Remarks

Validates a SignedMessage using the public half of the specified Ed25519 key pair.
