Digests / MD5 / MD5

An object for calculating MD5 hashes. Each hash calculation should instantiate its own MD5 instance.

Example:

    digest := MD5 clone
    digest appendSeq("this is a message")
    out := digest md5String

appendSeq(aSequence)

Appends aSequence to the hash calculation. Returns self.
md5

Completes the MD5 calculation and returns the hash as a Buffer. Once this method is called, append() should not be called again on the receiver or it will raise an exception.
md5String

Returns a string containing a hexadecimal representation of the md5 hash.
