Updates: Calculating CRC32 (and MDA5 and SHA-1) From .NET

Update23 Oct 2003

  • Upped the FileStream buffer size to 8192 bytes, which improves performance.
  • Added SHA-1 and MD5 calculations using the Framework Cryptography classes. These algorithms generate longer hash values but perform similarly to CRC32 and are more secure and resistant.

  • VB Code updated with a much cleaner, shorter and very fast algorithm supplied by Paul. Thanks!
