In SHA-512, the registers ‘a’ to ‘h’ are obtained by taking the first 64 bits of the fractional parts of the cube roots of the first 8 prime numbers.

Secure Hash Algorithms (SHA) are a family of cryptographic hash functions that are used to encrypt data. SHA is a modified version of MD5.  SHA's hash function uses bitwise operations, modular additions, and compression functions to produce a fixed-size string that looks different from the original data. A small change to the original data produces a different encrypted output, which is known as the avalanche effect.  SHA's primary goal is to produce a unique hash value for each input message.

Secure Hash Algorithms (SHA) are a family of cryptographic hash functions that are used to encrypt data. SHA is a modified version of MD5. 

SHA's hash function uses bitwise operations, modular additions, and compression functions to produce a fixed-size string that looks different from the original data. A small change to the original data produces a different encrypted output, which is known as the avalanche effect. 
SHA's primary goal is to produce a unique hash value for each input message. SHA-1 makes sure that two different messages are unlikely to produce the same hash value, making it resistant to collision attacks. 

SHA is used in a variety of methods, including:
Hashing data
Certificate files
Cryptocurrencies like bitcoin
Transport layer security (TLS)
Secure socket layer (SSL)
Digital signatures
S/MIME email certificates
PGP
IPsec 

All SHA-family algorithms are subject to official validation by the Cryptographic Module Validation Program (CMVP).
