-=head1 NAME

-BIO_f_cipher, BIO_set_cipher, BIO_get_cipher_status, BIO_get_cipher_ctx - cipher BIO filter
-
-=head1 SYNOPSIS
-
- #include <openssl/bio.h>
- #include <openssl/evp.h>
-
- BIO_METHOD *	BIO_f_cipher(void);
- void BIO_set_cipher(BIO *b,const EVP_CIPHER *cipher,
-		unsigned char *key, unsigned char *iv, int enc);
- int BIO_get_cipher_status(BIO *b)
- int BIO_get_cipher_ctx(BIO *b, EVP_CIPHER_CTX **pctx)
-
-=head1 DESCRIPTION
-
-BIO_f_cipher() returns the cipher BIO method. This is a filter
-BIO that encrypts any data written through it, and decrypts any data
-read from it. It is a BIO wrapper for the cipher routines
-EVP_CipherInit(), EVP_CipherUpdate() and EVP_CipherFinal().
-
-Cipher BIOs do not support BIO_gets() or BIO_puts(). 
-
-BIO_flush() on an encryption BIO that is being written through is
-used to signal that no more data is to be encrypted: this is used
-to flush and possibly pad the final block through the BIO.
-
-BIO_set_cipher() sets the cipher of BIO B<b> to B<cipher> using key B<key>
-and IV B<iv>. B<enc> should be set to 1 for encryption and zero for
-decryption.
-
-When reading from an encryption BIO the final block is automatically
-decrypted and checked when EOF is detected. BIO_get_cipher_status()
-is a BIO_ctrl() macro which can be called to determine whether the
-decryption operation was successful.
-
-BIO_get_cipher_ctx() is a BIO_ctrl() macro which retrieves the internal
-BIO cipher context. The retrieved context can be used in conjunction
-with the standard cipher routines to set it up. This is useful when
-BIO_set_cipher() is not flexible enough for the applications needs.
-
-=head1 NOTES
-
-When encrypting BIO_flush() B<must> be called to flush the final block
-through the BIO. If it is not then the final block will fail a subsequent
-decrypt.
-
-When decrypting an error on the final block is signalled by a zero
-return value from the read operation. A successful decrypt followed
-by EOF will also return zero for the final read. BIO_get_cipher_status()
-should be called to determine if the decrypt was successful.
-
-As always, if BIO_gets() or BIO_puts() support is needed then it can
-be achieved by preceding the cipher BIO with a buffering BIO.
-
-=head1 RETURN VALUES
-
-BIO_f_cipher() returns the cipher BIO method.
-
-BIO_set_cipher() does not return a value.
-
-BIO_get_cipher_status() returns 1 for a successful decrypt and 0
-for failure.
-
-BIO_get_cipher_ctx() currently always returns 1.
