- ECDsa.cs
- Source:
- ECDsa.cs
Generates a digital signature for the specified hash value.
public:
abstract cli::array <System::Byte> ^ SignHash(cli::array <System::Byte> ^ hash);
public abstract byte[] SignHash (byte[] hash);
abstract member SignHash : byte[] -> byte[]
Public MustOverride Function SignHash (hash As Byte()) As Byte()
Parameters
- hash
- Byte[]
The hash value of the data that is being signed.
Returns
A digital signature for the specified hash value.
Exceptions
The hash
parameter is null
.

SignHash(ReadOnlySpan<Byte>)
- Source:
- ECDsa.cs
- Source:
- ECDsa.cs
- Source:
- ECDsa.cs
Computes the ECDSA signature for the specified hash value.
public:
cli::array <System::Byte> ^ SignHash(ReadOnlySpan<System::Byte> hash);
public byte[] SignHash (ReadOnlySpan<byte> hash);
member this.SignHash : ReadOnlySpan<byte> -> byte[]
Public Function SignHash (hash As ReadOnlySpan(Of Byte)) As Byte()
Parameters
- hash
- ReadOnlySpan<Byte>
The hash value of the data that is being signed.
Returns
A digital signature for the specified hash value.
Exceptions
An error occurred in the signing operation.
Remarks
This method will use IeeeP1363FixedFieldConcatenation to encode the the signature. To use a different signature format, use SignHash(ReadOnlySpan<Byte>, DSASignatureFormat).
