OpenSSL.EVP.Verify

Description

Message verification using asymmetric cipher and message digest algorithm. This is an opposite of OpenSSL.EVP.Sign.

Synopsis

data VerifyStatus = VerifySuccess | VerifyFailure verify :: Digest -> String -> PKey -> String -> IO VerifyStatus verifyBS :: Digest -> String -> PKey -> ByteString -> IO VerifyStatus verifyLBS :: Digest -> String -> PKey -> LazyByteString -> IO VerifyStatus

Documentation

data VerifyStatus

VerifyStatus represents a result of verification. Constructors VerifySuccess VerifyFailure Instances Eq VerifyStatus Show VerifyStatus Typeable VerifyStatus

verify

:: Digest message digest algorithm to use -> String message signature -> PKey public key to verify the signature -> String input string to verify -> IO VerifyStatus the result of verification verify verifies a signature and a stream of data. The string must not contain any letters which aren't in the range of U+0000 - U+00FF.

verifyBS

:: Digest message digest algorithm to use -> String message signature -> PKey public key to verify the signature -> ByteString input string to verify -> IO VerifyStatus the result of verification verifyBS verifies a signature and a chunk of data.

verifyLBS

:: Digest message digest algorithm to use -> String message signature -> PKey public key to verify the signature -> LazyByteString input string to verify -> IO VerifyStatus the result of verification verifyLBS verifies a signature of a stream of data.
