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. http://certificate.fyicenter.com/2033_OpenSSL_rsautl_-Encrypt_Large_File_with_RSA_Key.html

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.) http://certificate.fyicenter.com/2032_OpenSSL_rsautl_data_too_large_for_key_size_Error.html

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.
