VerifyHash(Byte[], Byte[], DSASignatureFormat)

Source:

ECDsa.cs

Verifies that a digital signature is valid for the provided hash.

public:
 bool VerifyHash(cli::array <System::Byte> ^ hash, cli::array <System::Byte> ^ signature, System::Security::Cryptography::DSASignatureFormat signatureFormat);

public bool VerifyHash (byte[] hash, byte[] signature, System.Security.Cryptography.DSASignatureFormat signatureFormat);

member this.VerifyHash : byte[] * byte[] * System.Security.Cryptography.DSASignatureFormat -> bool

Public Function VerifyHash (hash As Byte(), signature As Byte(), signatureFormat As DSASignatureFormat) As Boolean

Parameters

hash

Byte[]

The signed hash.

signature

Byte[]

The signature to verify.

signatureFormat

DSASignatureFormat

The encoding format for signature.

Returns

Boolean

true if the digital signature is valid for the provided data; otherwise, false.

Exceptions

ArgumentNullException

hash or signature is null.

ArgumentOutOfRangeException

signatureFormat is not a known format.

CryptographicException

An error occurred in the verification operation.

VerifyHash(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>, DSASignatureFormat)

Source:

Returns

Boolean

true if the signature is valid; otherwise, false.

Exceptions

ArgumentNullException

hash or signature is null.

VerifyHash(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>)

Source:

ECDsa.cs
