Type: array<System. . :: . .Byte> [] () [] []
The data that was signed.
- halg
Type: System.Security.Cryptography. . :: . .HashAlgorithm
The hash algorithm used to create the hash value of the data.
- signature
Type: array<System. . :: . .Byte> [] () [] []
The signature data to be verified.
Return Value
Type: System. . :: . .Boolean
