The Hyper Hasher Suite will fulfill all your file hashing needs. Hyper Hasher allows you to calculate 26 different hash/checksum and HMAC values for any file on your system, while the HashFile utility adds support for MD5 & SFV file creation and verification. These tools feature advanced options including a unique customizable interface, configuration saving, optional windows shell integration, Pentium 4 optimizations for speed, and much more!

Free, fast calculator to compute hash, checksum, HMAC values for file, text and hex string. Supports popular message digest and check sum algorithms: MD2,MD4,MD5, SHA1,SHA2, RIPEMD160,PANAMA,TIGER, CRC32,ADLER32, and the hash used in eMule/eDonkey (eDonkey2000,ed2k). With this tool you can test for corruption FTP download/upload transfers, compare music,audio,video,game,image files, verify a CD, perform checking of mp3,mpeg,vcd,iso,zip downloads.

FileArmor is an easy to use, fast and high-secure defence for your files and folders. It uses an optimized AES implementation that conforms to FIPS-197, and a SHA1 implementation that conforms to FIPS-180-1. The key-size can be 128, 192 or 256 bits. The optimized AES version allows very fast speed of encryption/decryption. FileArmor includes a build-in tool for secure wiping of files.
