The files (.sfv & .md5) your need for check my files (Files Validation). SFV is an abbreviation for simple file verification, a file format for storing CRC32 checksums of files in order to verify the integrity of files. http://en.wikipedia.org/wiki/SFV MD5 In cryptography, MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An MD5 hash is typically a 32-character hexadecimal number. Recently, a number of projects have created MD5 "rainbow tables" which are easily accessible online, and can be used to reverse many MD5 strings into their original meanings. MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function, MD4. In 1996, a flaw was found with the design of MD5; while it was not a clearly fatal weakness, cryptographers began to recommend using other algorithms, such as SHA-1. In 2004, more serious flaws were discovered making further use of the algorithm for security purposes questionable. http://en.wikipedia.org/wiki/Md5 NOTE: The "hkSFV 2.0.1 (prog for check SFV + MD5).rar" is the program to check or make .SFV and .MD5 (validation files).
