When you download a file, it is important to check its authenticity and integrity. HQLator is a Cryptographic Hash Calculator computing file checksums and message digests - a unique and compacted representation of downloaded and local files. Message digest ensures data integrity and guarantees that your files have not been altered by unauthorized or unknown means. HQLator supports the following cryptographic standards: CRC-32, Adler-32, MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, RIPE-128, RIPE-160, RIPE-256, RIPE-320. A calculated digest can be saved as a text file for future verification.
