About SHA-1 Hash
SHA-1 (Secure Hash Algorithm 1) produces a 160-bit (40 hexadecimal character) hash value. It was designed by the NSA and was widely used for security applications.
Note: SHA-1 is considered cryptographically broken and should not be used for security purposes. For secure hashing, use SHA-256 or SHA-512 instead.
