MD5 hash and PHP?

[KeithMcL]

Recently I bought Professional PHP Programming and am on Chapter 9 at the moment (not as fast as yourself Wayne ) and out of the blue came a mention of MD5 hash.

Has anyone got any info on what it is and how it works. I believe it's something to do with creating 32 character numbers randomly. Am I right?

Much Appreciated.

Hashing is commonly used with encryption, another common use for the MD5 hash is to generate session keys on websites.
