HashCalc is a completely free super document "fingerprint" checker. We know that everyone's fingerprints are different. Through fingerprint identification, the police can identify suspects according to fingerprints. So, do the files in the computer have fingerprints? The answer is yes, that is "digital signature". The "digital signature" of each file is different, which is equivalent to a person's "fingerprint". By identifying its "digital signature", we can judge whether they are the same file, which not only saves hard disk space, but also prevents Trojan horses and viruses.
At present, the most commonly used "digital signature" methods are MD5, SFV, SHA 1, CRC32 (the mcrc adopting this method is WinRAR) and so on. Digital signatures recognized by HashCalc include MD5, SHA 1, CRC32, MD4, SHA256, SHA384, SHA5 12.
