Expand description
\brief This function performs a PKCS#1 v1.5 encryption operation (RSAES-PKCS1-v1_5-ENCRYPT).
\param ctx The initialized RSA context to use.
\param f_rng The RNG function to use. It is mandatory and used for
padding generation.
\param p_rng The RNG context to be passed to \p f_rng. This may
be \c NULL if \p f_rng doesn’t need a context argument.
\param ilen The length of the plaintext in Bytes.
\param input The input data to encrypt. This must be a readable
buffer of size \p ilen Bytes. It may be \c NULL if
ilen == 0
.
\param output The output buffer. This must be a writable buffer
of length \c ctx->len Bytes. For example, \c 256 Bytes
for an 2048-bit RSA modulus.
\return \c 0 on success. \return An \c MBEDTLS_ERR_RSA_XXX error code on failure.
