WebPGP works through a combination of cryptography, data compression, and hashing techniques.It is similar to other popular encryption methods such as Kerberos, which authenticates network users, secure sockets layer (SSL), which secures websites, and the Secure File Transfer Protocol (SFTP), which protects data in motion.. PGP uses the public … WebSHA stands for secure hashing algorithm. SHA is a modified version of MD5 and used for hashing data and certificates. A hashing algorithm shortens the input data into a smaller form that cannot be understood by using bitwise operations, modular additions, and compression functions. You may be wondering, can hashing be cracked or decrypted?
