How Do I Implement Symmetric Key Encryption In Ethereum?
3 min readAug 2, 2022
With symmetric-key, we have the ability to encrypt with a key and then decrypt with the same key. The most typical method of this is AES. But, AES is a power-intensive method which can take up quite a bit of memory. It is thus not well matched to Ethereum, and which will charge gas for the processing. Well, in our toolbox is the Keccak-256 hashing method, adding points, multiplying points and…
