What is SHA-1 (Secure Hash Algorithm 1) ?

SHA-1, or Secure Hash Algorithm 1, is a cryptographic hash function that produces a 160-bit (20-byte) hash value. It's designed to take an input message, no matter how large, and produce a fixed-size output hash value. SHA-1 is commonly used in various security applications and protocols to ensure data integrity, such as in digital signatures, SSL certificates, and HTTPS.

However, vulnerabilities have been discovered in SHA-1 over time, including the ability to generate hash collisions, where two different inputs produce the same hash value. Consequently, its security has been weakened, and its usage in security-sensitive applications has been discouraged in favor of more secure hash functions like SHA-256.
