MD5 Hash a String (such as a password string)

See more Encryption Examples

Demonstrates how to MD5 hash a string to get MD5 hash in hex encoded string representation. (The MD5 hash is 16 bytes, and therefore a hex encoded MD5 hash would be 32 chars.) Delphi ActiveX

// The hex string will be uppercase.  Your application
// can easily convert it to lowercase if desired via non-Chilkat means.
