SHA1 Online Calculator - Free Online Hash Calculators

SHA1 hash calculator

Here you can calculate online SHA1 hashes for your strings. Put your string into form below and press "Calculate SHA1 hash". As a result you will get SHA1 hash of your string. If you need another hash calculators, for example: HAVAL160-5, HAVAL224-5, JOAAT or SHA3-384 you can find it into appropriate section.

About SHA-1 hash algorithm

In cryptography, SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function which takes an input and produces a 160-bit (20-byte) hash value known as a message digest – typically rendered as a hexadecimal number, 40 digits long. It was designed by the United States National Security Agency, and is a U.S. Federal Information Processing Standard.

Since 2005 SHA-1 has not been considered secure against well-funded opponents, and since 2010 many organizations have recommended its replacement by SHA-2 or SHA-3. Microsoft, Google, Apple and Mozilla have all announced that their respective browsers will stop accepting SHA-1 SSL certificates by 2017.

In 2017 CWI Amsterdam and Google announced they had performed a collision attack against SHA-1, publishing two dissimilar PDF files which produced the same SHA-1 hash.
