SHA-1

SHA-1, also known as Secure Hash Algorithm 1, was developed as a cryptographic hash algorithm for communication protocols and applications, including TLS, SSL, and SSH.

SHA-1 (Secure Hash Algorithm 1) takes the cryptographic hash function as input, which produces a hash value different from the original data. SHA algorithms are one-way functions; they cannot be decrypted back into original data, making original data secure from attackers.
