What Is a SHA-1 Generator?
The SHA-1 Generator produces a 160-bit (20-byte) hash value from text input, typically rendered as a 40-character hexadecimal number. SHA-1 (Secure Hash Algorithm 1) was designed by the United States National Security Agency. Like MD5, SHA-1 is now considered cryptographically broken against well-funded attackers.
