Data.Digest.Pure.MD5

It is suggested you use the 'crypto-api' class-based interface to access the MD5 algorithm. Either rely on type inference or provide an explicit type:

  hashFileStrict = liftM hash' . B.readFile
  hashFileLazyBS = liftM hash . B.readFile

Types

datadata MD5Context

Source#

The type for final results.

datadata MD5Digest

Source#

After finalizing a context, using md5Finalize, a new type is returned to prevent 're-finalizing' the structure.

Static data

valuemd5InitialContext :: MD5Context

Source#

The initial context to use when calling md5Update for the first time

Functions

valuemd5 :: ByteString -> MD5Digest

Source#

Processes a lazy ByteString and returns the md5 digest. This is probably what you want. You can use show to produce the standard hex representation.

valuemd5Update :: MD5Context -> ByteString -> MD5Context

Source#

Alters the MD5Context with a partial digest of the data.

The input bytestring MUST be a multiple of the blockSize or bad things can happen (incorrect digest results)!

valuemd5Finalize :: MD5Context -> ByteString -> MD5Digest

Source#

Closes an MD5 context, thus producing the digest.

valuemd5DigestBytes :: MD5Digest -> ByteString

Source#

The raw bytes of an MD5Digest. It is always 16 bytes long.

You can also use the Binary or Serialize instances to output the raw bytes. Alternatively you can use show to produce the standard hex representation.

Crypto-API interface

classclass (Serialize d, Eq d, Ord d) => Hash ctx d | d -> ctx, ctx -> d where

Source#

The Hash class is intended as the generic interface targeted by maintainers of Haskell digest implementations. Using this generic interface, higher level functions such as hash and hash' provide a useful API for comsumers of hash implementations.

Any instantiated implementation must handle unaligned data.

Minimum complete definition: outputLength, blockLength, initialCtx, updateCtx, and finalize.

Methods

outputLength :: Tagged d BitLength
blockLength :: Tagged d BitLength
initialCtx :: ctx
updateCtx :: ctx -> ByteString -> ctx
finalize :: ctx -> ByteString -> d
hash :: Hash ctx d => ByteString -> d
Hash a lazy ByteString, creating a digest
hash' :: Hash ctx d => ByteString -> d
Hash a strict ByteString, creating a digest
