MD5 Checksum Calculator previously called (RiMD5), is a tiny portable freeware utility that can be used to generate, calculate, compare and validate checksum values or MD5 (Message Digest number 5) of specified files. This checksum generator takes the input message of the chosen file and creates a resulting 128 bit fingerprint for the file. It is nearly impossible to produce two messages having the exact same message digest, hash or checksum.
SFV Ninja is a Simple File Verification checksum calculator; A tool that can be used to either verify a checksum file or or create a checksum file. Creation or validation of CRC32, MD5, SHA-1, or SHA-256 checksums are supported. The checksum of multiple files or even entire folders of files can be calculated or validated all at once.
HashMyFiles is a portable free checksum calculator. This hash checker works by calculating and showing the MD5, SHA, and CRC32 hashes of a file or files. It supports hash checking a folder of several files at once or via direct file selection.
IgorWare Hasher is a SHA-1, MD5 and CRC32 hash creator or hash generator for Windows. This checksum calculator can be used to generate a checksum for a single file. Checksums are used to verify file integrity by using verification files.
MultiHasher is a File Hash Generator or Checksum Calculator. Offered as portable freeware, it can be used to validate, check or create MD5, SHA-1, CRC32, SHA-256, SHA-384, SHA-512 hashes or checksums. The tool supports drag and drop functionality, can be used to calculate hash values for multiple files at ince, and offers unicode support.
