What exactly is the MessageDigest Class/ Message Digests etc
Posted on 2002-03-21
The MessageDigest Class from a definaition i have seen provides functionality for cryptographically secure message digests such as SHA1 or MD5.
What I want to know is what are message digests (SHA1 and MD5 are given in the definition I've seen but not sure what they are either)?
Are message digests for email messages or for some other form of message. And if so then what is used for email messaging?
