What is RapidCRC?
RapidCRC is a tool for windows for checking and creating CRC32 and MD5 checksums; this comprises:

  • SFV files
  • MD5 files
  • specialty: direct support for CRC32 in the filename (common for anime releases; for example "MyFile [45DEF3A0].avi")

This helps you to check and ensure that your files are OK and not corrupted.

Goal is to use the fastest available open source (assembly) implementations for this task. Currently these implementations are used in RapidCRC:

  • CRC32: i386 assembly implementation (one byte table lookup)
  • MD5: OpenSSL MD5 i386 assembly implementation
  • MD5: reference implementation from RFC (much slower; available at compile time. Not used in the release version of RapidCRC)

These are currently considered to be the fastest existing implementations(*). If you know of even faster implementations please drop me a note.
