Web26 de nov. de 2024 · On Android, the answer is no. So the Java runtime throws an exception and we detect it that with CheckJNIExceptions. Since we get an exception, EcKeyCreateByOid returns NULL. We check for a NULL result here: runtime/src/libraries/System.Security.Cryptography/tests/DefaultECDsaProvider.Android.cs … WebYes, you can encrypt data without any padding using the OpenSSL "rsautl -encrypt -raw" command. But you need to remember the following: No padding requires the input data to be the same size as the RSA key. No padding requires the integer value represented by the input data must be smaller than the modulus of the RSA key.

WebOpenSSL does have a large number of compile-time options to control what features are built. I believe that the SSL functions use BIO s underneath, so you'll still need those, but there's a lot of other functionality you can probably go without (like ciphers you won't use, envelope encryption, S/MIME support...).

Web26 de jun. de 2014 · You would need an arbitrarily large key ;) But OpenSSL limits your key size to 16K-bits. So you can't make the keys arbitrarily large. Plus, its hard to generate those large keys. Generation time grows with key size, and you could spend a couple of days generating large keys.
