RSA secret key setup.

Parameters

[out]	key	The initialized secret key.
[out]	key_mem	Key memory. Length OCRYPTO_RSA_KEY_SIZE(bits). Must have same lifetime as key.
	n	The RSA modulus, unsigned big-endian.
	n_len	Length of n.
	d	The secret exponent, unsigned big-endian.
	d_len	Length of d. Must be <= n_len.

Return values

-1	If the input length is invalid.
0	On success.

Remarks

The n and d values can be read directly from the corresponding value parts of a DER encoded RSAPrivateKey.
