WebFeb 10, 2024 · The application supplied digest value must be computed using SHA-384 and must be 48 bytes in length. RS512 - RSASSA-PKCS-v1_5 using SHA-512. The application supplied digest value must be computed using SHA-512 and must be 64 bytes in length. RSNULL - See RFC2437, a specialized use-case to enable certain TLS scenarios. Note WebJun 10, 2024 · To encrypt data, you can use RSA. 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. C# crack office 2019 offline
