c. Simple Hash Algorithm-1
d. Superior Hash Algorithm-1

ANSWER: Secure Hash Algorithm-1
 
Google, Dutch partner crack SHA-1A collaboration between Google's research unit and a Dutch institute on Thursday cracked a widely used cryptographic technology SHA-1.

This technology that has been one of the key building blocks of internet security, is known as Secure Hash Algorithm 1 or currently used to verify the integrity of digital files and signatures that secure credit card transactions as well as Git open-source software repositories.

Researchers were able to demonstrate a "collision attack" using two different PDF files with the same SHA-1 fingerprint, but with different visible content.

Moving forward, it's more urgent than ever for security practitioners to migrate to safer cryptographic hashes such as SHA-256 and SHA-3.

SHA-1: Know More
  • In cryptography, SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function.
  • It is designed by the United States National Security Agency.
  • It is a U.S. Federal Information Processing Standard published by the United States NIST.
  • SHA-1 produces a 160-bit (20-byte) hash value known as a message digest.
