The SHA-256 algorithm represents Secure Hash Calculation 256-digit. Other digits are also available in the SHA algorithm but are not as compatible as SHA-256. This mining algorithm applies in many ways, such as verifying digital signatures, SSL handshake, and Hashing passwords for encryption. The best thing about the SHA-256 is its high-level encryption, possibly due to several factors such as its irreversibility, bits length and hash digest. It is a great performer in the blockchain industry and encrypts all the data with efficient mining results. SHA-256 is capable of mining coins like Bitcoin, Bitcoin Cash, Litecoin cash, Namecoin, PRIZM, etc.
