WebJun 10, 2024 · For the key length, you should use at least 2048 (NSA recommends 3072 or larger ref ). Note that RSA can only encrypt data up to the key length (including padding). So, with a key of 2048 bits, you cannot encrypt a blob of 4096 bits. You'll need to split it into 2 blobs and encrypt them separately.

It uses the same key for encryption and decryption processes, so the sender and the receiver, both must know — and use — the same secret key. WebAlthough it is not possible to "decrypt" password hashes to obtain the original passwords, it is possible to "crack" the hashes in some circumstances.
