Unfortunately the OpenSSL maintainers have utterly abdicated any responsibility for helping secure users, and has gone with poor defaults, obligating us to fill the hole. While the trusty old PHP crypt function is perfect for encrypting and authenticating passwords, the hash it creates is one-way and doesn't allow for decryption. The data being read from fd is assumed to have come from DES_enc_write() and is decrypted using sched for the key schedule and iv for the initial vector. 5 form plaintext, the correct encryption key will be replaced by garbage, and the message cannot be decoded, but if the RSA decryption fails, the correct encryption key is used and the recipient will not notice the attack.
