SHA2

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.

Fast, highly optimized implementation of hash and checksum algorithms: MD2, MD4, MD5, SHA-1, SHA-2(256,384,512), RIPEMD(128,160,256,320), PANAMA, TIGER, CRC-32, CRC-16, CRC-CCITT, ADLER32. The library allows to calculate hashes (message digests), checksums and HMACs for files, memory blocks, strings, streaming data. Has no external dependencies such as MFC DLL, COM/DCOM or other component. The help file has examples in Visual Basic(VB), C, C++.

Iside compares files and folders by computing their hash code (MD5,SHA1,...). Right click on a file, select Copy and by right clicking on another file you will discover if they are equal. Includes file comparison, hash displaying tool plus a complete folder comparison tool.
The hash functions allow to determine if two files are different even if their size is the same.
Ideal tool for configuration managers, programmers, deployers.

axsStrongBox is a COM component which provides secure data encryption (public and private key) using industry standard, strong algorithms such as Rijndael, RSA and others. It also provides digital signatures, hashing, GZIP and Base64 capability. It can be easily integrated with Visual Basic, VC++, Delphi and VBScript. A flexible password system allows you to use PIN's, passwords, passphrases or binary keys.
