- Use the Blowfish cipher to improve password security
- In addition to its common use for generating hashes used to verify the integrity of a downloaded file, the MD5 algorithm is also used widely for password authentication systems. It became the most common Unix password hash algorithm in the 1990s, in fact, and many Unix-like systems still default...

- Use MD5 hashes to verify software downloads
- Professor Ronald Rivest of MIT created the MD5 cryptographic hash function in 1991 to replace the earlier MD4 algorithm. It employs a 128-bit hash value, typically expressed as a 32-character hexadecimal number. For instance, an MD5 hash generated from an OpenOffice.org download (v2.3.0 for Win32, English language) looks...

- Create key-value data associations by understanding the benefits of Perl hashes
- One of Perl's mostinteresting data structures is the hash, which makes it possible to create key-valueassociations between data fragments. These hashes, although far more versatilethan plain-vanilla numerically-indexed arrays, are often intimidating to thenovice user. And that's where this document comes in - it provides a crashcourse in creating Perlhashes, adding...

- How do I... Serialize a hash table in C# when the application requires it?
- Unfortunately, the .NET Framework does not allow serialization of any object that implements the IDictionary interface. This restriction includes, but is not limited to, hash tables. Like many developers, I have run into this restriction head on and been disappointed about the inability for serialization on hash tables. ...
