WebADR 013: Need for symmetric cryptography Context. We require symmetric ciphers to handle how we encrypt keys in the sdk, and to potentially encrypt priv_validator.json in tendermint.. Currently we use AEAD’s to support symmetric encryption, which is great since we want data integrity in addition to privacy and authenticity. WebSymmetric cryptography With symmetric cryptography (or symmetric-key encryption), the Figure 1. key encryption Symmetric key ciphers are valuable because: It is relatively inexpensive to produce a strong key for these ciphers. The keys tend to be much smaller for the level of protection they afford.

WebSymmetric encryption is the process of converting plaintext into ciphertext and vice versa using the same key. An encryption key is a random string of bits used to encrypt or decrypt data. It is, therefore, important that key is transferred between the sender and recipient using secure methods. RC4, RC5, RC6, IDEA, Blowfish, AES, DES and 3DES ...
