Encryption plays an essential role in SSL that uses SHA-2 hash algorithm.
The SHA-2 family includes hash values like SHA-224, 256, 384 and 512. Earlier, SHA-1 was in force but somehow it seemed weak algorithm against attacks. Currently, Most of certificate authorities offer SHA-256 encryption for online security of transactions.
The stronger encryption you use, the more your information is secured.
Encryption creates a secure channel through which sensitive information passes
