Encryption changes data into a form that can only be read by the intended receiver. 256-Bit Encryption refers to the size of the decryption key used to unscramble encrypted data. 256-Bit encryption is considered computationally infeasible to crack and is known as a very strong SSL certificate.

What Do 128 Bit and 256 Bit Mean in Encryption? As we discussed earlier, when talking about 128 bit vs 256 bit encryption, the numbers 128 and 256 represent the encryption key length. It means that your data is encrypted (locked) and decrypted (unlocked) using a key of 128 or 256 bits. (Note: Every bit represents a binary digit, either 1 or 0.) What is the current version of SSL/TLS? TLS 1.3, defined in August 2018 by RFC 8446, is the most recent version of SSL/TLS. TLS 1.2 was defined in August 2018 and also remains in wide use. Versions of SSL/TLS prior to TLS 1.2 are considered insecure and should no longer be used. Support for SSL 2.0 (and weak 40-bit and 56-bit ciphers) was removed completely from Opera as of version 10. SSL 3.0. SSL 3.0 improved upon SSL 2.0 by adding SHA-1–based ciphers and support for certificate authentication. From a security standpoint, SSL 3.0 should be considered less desirable than TLS 1.0. Feb 04, 2015 · Ciphers: SSL uses one of a large variety of possible “ciphers” to perform the symmetric encryption. Use of a poor/weak cipher can result in fast SSL that is easily compromised. Currently, it is recommended that one use 128-bit or stronger AES encryption as your cipher. See: 256-bit AES Encryption for SSL and TLS: Maximal Security. Symmetric 256-bit encryption. RSA public-key SHA-2 algorithm (supports hash functions: 256, 384, 512) ECC public-key cryptography (supports hash functions: 256 and 384) Supports 2048-bit public key encryption (3072-bit and 4096-bit available)

256 Bit Encryption. When a Web browser points to a secured domain, a level of encryption is established based on the type of SSL Certificate, the client Web browser, operating system, and host server’s capabilities. That is why SSL Certificates feature a range of encryption levels, such as "up to 256-bit". The bottom line here is that while 128 bit SSL encryption will take less time to crack than 256-bit encryption, it’s still reasonably safe to use. Having said that, these are all contingent on AES being implemented correctly, with sufficient entropy, and without falling victim to side-channel attacks, insecure passwords, etc. Encryption Resources In SSL, the server key is used only to transmit a random 256-bit key (that one does not have mathematical structure, it is just a bunch of bits); roughly speaking, the client generates a random 256-bit key, encrypts it with the server's RSA public key (the one which is in the server's certificate and is a "2048-bit key"), and sends the result
