R:HASH 11

Introduction and Features

The RHASH Plugin is used to generate a hash value from internal cryptographic functions. Based upon a text string value or file name, R:HASH uses one of many available hash functions to generate the hash value (also called a "message digest" or a "checksum") as a sort of "digital fingerprint" of the text string or document. The resulting fixed-size hash value is a concise representation of the source input from which it was computed. Of the output formats, Hexadecimal, Hexadecimal lowercase, MIME Base 64, UU Coding, and XX Coding are available.

R:HASH includes the following hash functions:

• MD4
• MD5
• SHA
• SHA1
• RMD128
• RMD160
• RMD256
• RMD320
• HAVAL256
• HAVAL224
• HAVAL192
• HAVAL160
• HAVAL128
• SAPPHIRE320
• SAPPHIRE288
• SAPPHIRE256
• SAPPHIRE224
• SAPPHIRE192
• SAPPHIRE160
• SAPPHIRE128
• SNEFRU
• SQUARE
• TIGER
• XOR16
• XOR32
• CRC16CCITT
• CRC16
• CRC32

The different hash functions can be used for a variety of computational purposes, including cryptography. Even small changes in the source input drastically alters the resulting output, also known as the avalanche effect.
