<title>Mcrypt ciphers</title>
|
|
<para>
|
|
Here is a list of ciphers which are currently supported by the mcrypt
|
|
extension. For a complete list of supported ciphers, see the defines at
|
|
the end of <filename>mcrypt.h</filename>. The general rule with the
|
|
mcrypt-2.2.x API is that you can access the cipher from PHP with
|
|
MCRYPT_ciphername. With the libmcrypt-2.4.x and libmcrypt-2.5.x API these constants also work,
|
|
but it is possible to specify the name of the cipher as a string with a
|
|
call to <function>mcrypt_module_open</function>.

<para>

|
You must (in <constant>CFB</constant> and <constant>OFB</constant> mode)
|
|
or can (in <constant>CBC</constant> mode) supply an
|
|
initialization vector (IV) to the respective cipher function. The
|
|
IV must be unique and must be the same when
|
|
decrypting/encrypting. With data which is stored encrypted, you
|
|
can take the output of a function of the index under which the
|
|
data is stored (e.g. the MD5 key of the filename).
|
|
Alternatively, you can transmit the IV together with the encrypted
|
|
data (see chapter 9.3 of &book.applied.cryptography; for a
|
|
discussion of this topic).
