Proposal to Add Secure Hash Algorithm ( SHA-1 ) Hashing Algorithm

[RgiriH]

Description

I would like to propose adding a SHA-1 hashing algorithm to our project. SHA-1 is a widely used cryptographic hash function that produces a 160-bit hash value, and it is often used for data integrity verification and digital signatures.

Rationale

• Data Integrity: Implementing SHA-1 will provide users with a reliable method to verify data integrity.
• Compatibility: Many existing systems and applications still rely on SHA-1 for hashing, making it a valuable addition.
• Educational Value: Including this algorithm can enhance the educational aspect of our project by showcasing a fundamental cryptographic concept.

Implementation Details

• The implementation will include:
  • A hashing function that processes input strings and returns the SHA-1 hash in hexadecimal format.
  • Unit tests to ensure the correctness of the implementation.
  • Documentation on how to use the SHA-1 function.

currently SHA1 is not available in most of the Javascript algorithm repositories which makes it difficult to use advance algorithms like SHA1 in JS , including SHA1 in this repo would be a great thing as this repo mainly focus on testing and education purpose .

I have made a pull request after following all the contributed guidelines
