Free command line utility for file multi-checksum generation and verification. Most common use: checking files for corruption. A hash/checksum calculation might be performed on data before transferring(downloading/uploading) it from one location to another. Making the same calculation after the transfer (download/upload) and comparing the former and latter results, you can check if the received data is corrupted or not.
Fsum allows to create/verify most popular file hashes (message digests) and checksums: MD2, MD4, MD5, SHA-1, SHA-2 (256,384,512), RIPEMD-160, PANAMA, TIGER, CRC-32, and the hash used in eDonkey (ed2k)/eMule tools; Very fast and easy to use. Recurses directories, works with large size files, supports .MD5 and .SFV file formats (automatically recognizes the format when verifying). Checks the integrity of data files notifying about any bad, incorrect or missing file. Compatible with: md5sum, MD5Summer, Easy SFV/MD5 Creator, SFV Checker/Verifier, WinSFV, Win CRC32. Version 2.52 fixes minor bugs.
