A Very Popular Hashing Function Sha1 Is No Longer Safe to Use. SHA-1 or ‘Secure Hash Algorithm 1’ is a cryptographic hash function that has been used by certificate authorities to sign SSL certificates. The CA/B Forum has announced the deprecation of the SHA-1 algorithm in favor of the newer and more secure SHA-2 hashing algorithms.

Windows 8 supports the SHA256 EV Code Signing Certificates; however, Windows 7 may only support SHA-1 EV Code Signing Certificates (Microsoft security advisory: Availability of SHA-2 code signing support for Windows 7 and Windows Server 2008 R2: March 10, 2015).

Secure Hash Algorithm 1: The Secure Hash Algorithm 1 (SHA-1) is a cryptographic computer security algorithm. It was created by the US National Security Agency in 1995, after the SHA-0 algorithm in 1993, and it is part of the Digital Signature Algorithm or the Digital Signature Standard (DSS).

The SHA1 hash function is now completely unsafe Researchers have achieved the first practical SHA-1 collision, generating two PDF files with the same signature SHA-1 conversion and SHA-1 reverse lookup

SHA512 : This hash function belong to hash class SHA-2, the internal block size of it is 64 bits. SHA1 : The 160 bit hash function that resembles MD5 hash in working and was discontinued to be used seeing its security vulnerabilities. Below code implements these hash functions.
