Preload OpenSSL ERR string data so that the formatted error messages are vaguely meaningful. Add OpenSSL error information to the RSA_public_encrypt() operation failure case in one-time key generation. For obsolescent OpenSSL versions (*cough* FIPS *cough*), pre-seed the PRNG before entering Cap mode, as old versions of OpenSSL are unaware of kernel RNG interfaces aside from /dev/random (such as the long-supported kern.arnd, or the slightly more recent getentropy(3) or getrandom(2)). (RSA_public_encrypt() wants a seeded PRNG to randomize the "PS" portion of PKCS 1.5 padding or the "MGF" pseudo-random function in OAEP padding.) Switch dumpon to encrypt the one-time key with OAEP padding (recommended since 1998; RFC2437) rather than the obsolescent PKCS 1.5 padding (1993; RFC2313). Switch decryptcore to attempt OAEP decryption first, and try PKCS 1.5 decryption on failure. This is intended only for transition convenience, and we should obsolete support for non-OAEP padding in a release or two.
