SHA-1 Hash Generator is a simple way to generate SHA-1 message digest from a text input provided by the user.
What is SHA-1Secure Hash Algorithm 1 or SHA-1 is a hash function that produces a 160-bit (20-byte) hash value known as a message digest. A SHA-1 hash value is typically rendered as a hexadecimal number, 40 digits long. SHA-1 was designed by the US National Security Agency (NSA).
Although there are still some use-case where SHA-1 is useful, it is no longer considered secure after cryptanalysts found attacks on it that suggests that the algorithm might not be secure enough for ongoing use in securing information.
