Hashing uses an algorithm to translate data of any size to a fixed length, resulting in a hash value, rather than the ciphertext produced by encryption algorithms. Hashing is used to verify that data has not been altered from its previous state during transmission.

RSA and OAEP: Choosing or not choosing the Hash Algorithm?

WebFeb 6, 2024 · OAEP padding should be prefered over PKCS. The weakness against collisions of the hash algorithm associated with OAEP is, to date, not of concern and should not be a decisive criterion. Relying on a shorter output hash allows encrypting larger strings. I am looking for the best security practices, whilst keeping maintenance as low as possible. WebMar 26, 2024 · The SHA-256 algorithm returns hash value of 256-bits, or 64 hexadecimal digits.
