sha256 :: PureByteSource src => src -> SHA256 Source #

Compute the sha256 hash of an instance of PureByteSource. Use this for computing the sha256 hash of a strict or lazy byte string.

sha256File :: FilePath -> IO SHA256 Source #

Compute the sha256 hash of a file.

sha256Source :: ByteSource src => src -> IO SHA256 Source #

Compute the sha256 hash of a general byte source.

HMAC computation using SHA256

hmacSha256 Source #

Arguments

:: PureByteSource src 
=> Key (HMAC SHA256)

Key to use

-> src

pure source whose hmac is to be computed

-> HMAC SHA256 

Compute the message authentication code using hmac-sha256.

hmacSha256File Source #

Arguments

:: Key (HMAC SHA256)

Key to use

-> FilePath

File whose hmac is to be computed

-> IO (HMAC SHA256) 

Compute the message authentication code for a file.

hmacSha256Source :: ByteSource src => Key (HMAC SHA256) -> src -> IO (HMAC SHA256) Source #

Compute the message authetication code for a generic byte source.
