WebA In most case, you should be able to use the OpenSSL "rsautl -encrypt -raw" command to encrypt input data of the same size as the RSA public key. But sometimes, you will get the "data too large for key size" error, if the integer value represented by the input data is larger than the modulus value of the RSA public key. WebYou cannot encrypt anything with RSA which is larger than the key size (minus some padding and header) which means that you cannot sign anything if the signature algorithms results in a value larger than the key. A hash digest is 256 bit for SHA-256 or 192 bit for (already insecure) SHA-1, i.e. way larger than 32 bit.

Nils. 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...). happiness dictionary definition

Web@bvj Then you aren't encrypting with a private key, as in, the private part of a key pair for an asymmetric cryptographic scheme. You're encrypting with a secret key. (Terminology isn't completely standardized, but most of the world uses “private key” only in the context of public-key cryptography, and uses “secret key” in the context of symmetric cryptography.)
