Fingerprint allows data to be monitored, detecting even the change of a single bit. If that doesn't suit you, our users have ranked more than 50 alternatives to checksum and many of them is open source so hopefully you can find a suitable replacement. OSI Certified is a certification mark of the Open Source Initiative. Calculate MD5, SHA-1 and SHA-256 file hashes, and them compare them to an available checksum to se. Unfortunately, each of these systems is highly complex and can inflict all kinds of damage on data, much of the damage undetectable to humans. The best open source alternative to checksum is HashCheck Shell Extension. Jacksum is a free checksum utility written in Java (Adler32, BSD sum, POSIX cksum. This approach means trusting all the software to which the data is exposed: operating systems, backup software, communications software, compression software, encryption software, and archiving software. Traditionally, the only way to preserve data was to take regular backups and hope that any unwanted changes that occurred would be major, obvious ones (such as loss of the disk). The Top 3 Algorithms Checksum Calculation Open Source Projects. If so much as a single bit in a single file in the directory tree has changed, fingerprint will detect it. This snapshot file can then be used to generate a list of files that have been created, deleted, or modified. Fingerprint scans a directory tree and generates a small transcript file containing the names and hashes of the files. Other great apps like AUTHENTiC - The Checksum Calculator are CHK Checksum Utility, Hasher, MultiHasher and HashCalc. The best alternative is fHash, which is both free and Open Source. Fingerprint - Fingerprint is a simple tool that can be used to verify the contents of a directory.įingerprint is a general purpose data integrity tool that uses cryptographic hashes to detect changes in files. There are more than 10 alternatives to AUTHENTiC - The Checksum Calculator for Windows, and Mac. Python module that wraps around hashlib and zlib to facilitate generating checksums / hashes of files and directories.
