For more information about the format of \fBarg\fR see \*(L"Pass Phrase Options\*(R" in \fIopenssl\fR\|(1). .IP "\fB\-e\fR" 4 .IX Item "-e" Encrypt the input data: this is the default. .IP "\fB\-d\fR" 4 .IX Item "-d" Decrypt the input data. .IP "\fB\-a\fR" 4 .IX Item "-a" Base64 process the data. This means that if encryption is taking place the data is base64 encoded after encryption. If decryption is set then the input data is base64 decoded before being decrypted. .IP "\fB\-base64\fR" 4 .IX Item "-base64" Same as \fB\-a\fR .IP "\fB\-A\fR" 4 .IX Item "-A" If the \fB\-a\fR option is set then base64 process the data on one line. .IP "\fB\-k password\fR" 4 .IX Item "-k password" The password to derive the key from. This is for compatibility with previous versions of OpenSSL. Superseded by the \fB\-pass\fR argument. .IP "\fB\-kfile filename\fR" 4 .IX Item "-kfile filename" Read the password to derive the key from the first line of \fBfilename\fR. This is for compatibility with previous versions of OpenSSL. Superseded by the \fB\-pass\fR argument. .IP "\fB\-md digest\fR" 4 .IX Item "-md digest" Use the specified digest to create the key from the passphrase. The default algorithm is sha\-256. .IP "\fB\-iter count\fR" 4 .IX Item "-iter count" Use a given number of iterations on the password in deriving the encryption key. High values increase the time required to brute-force the resulting file. This option enables the use of \s-1PBKDF2\s0 algorithm to derive the key. .IP "\fB\-pbkdf2\fR" 4 .IX Item "-pbkdf2" Use \s-1PBKDF2\s0 algorithm with default iteration count unless otherwise specified. .IP "\fB\-nosalt\fR" 4 .IX Item "-nosalt" Don't use a salt in the key derivation routines. This option \fB\s-1SHOULD NOT\s0\fR be used except for test purposes or compatibility with ancient versions of OpenSSL. .IP "\fB\-salt\fR" 4 .IX Item "-salt" Use salt (randomly generated or provide with \fB\-S\fR option) when encrypting, this is the default. .IP "\fB\-S salt\fR" 4 .IX Item "-S salt" The actual salt to use: this must be represented as a string of hex digits. .IP "\fB\-K key\fR" 4 .IX Item "-K key" The actual key to use: this must be represented as a string comprised only of hex digits. If only the key is specified, the \s-1IV\s0 must additionally specified using the \fB\-iv\fR option. When both a key and a password are specified, the key given with the \fB\-K\fR option will be used and the \s-1IV\s0 generated from the password will be taken. It does not make much sense to specify both key and password. .IP "\fB\-iv \s-1IV\s0\fR" 4 .IX Item "-iv IV" The actual \s-1IV\s0 to use: this must be represented as a string comprised only of hex digits. When only the key is specified using the \fB\-K\fR option, the \&\s-1IV\s0 must explicitly be defined. When a password is being specified using one of the other options, the \s-1IV\s0 is generated from this password. .IP "\fB\-p\fR" 4 .IX Item "-p" Print out the key and \s-1IV\s0 used. .IP "\fB\-P\fR" 4 .IX Item "-P" Print out the key and \s-1IV\s0 used then immediately exit: don't do any encryption or decryption. .IP "\fB\-bufsize number\fR" 4 .IX Item "-bufsize number" Set the buffer size for I/O. .IP "\fB\-nopad\fR" 4 .IX Item "-nopad" Disable standard block padding. .IP "\fB\-debug\fR" 4 .IX Item "-debug" Debug the BIOs used for I/O. .IP "\fB\-z\fR" 4 .IX Item "-z" Compress or decompress encrypted data using zlib after encryption or before decryption. This option exists only if OpenSSL was compiled with the zlib or zlib-dynamic option. .IP "\fB\-none\fR" 4 .IX Item "-none" Use \s-1NULL\s0 cipher (no encryption or decryption of input). .IP "\fB\-rand file...\fR" 4 .IX Item "-rand file..." A file or files containing random data used to seed the random number generator. Multiple files can be specified separated by an OS-dependent character. The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for all others. .IP "[\fB\-writerand file\fR]" 4 .IX Item "[-writerand file]" Writes random data to the specified \fIfile\fR upon exit. This can be used with a subsequent \fB\-rand\fR flag. .SH "NOTES" .IX Header "NOTES" The program can be called either as \fBopenssl cipher\fR or \&\fBopenssl enc \-cipher\fR. The first form doesn't work with engine-provided ciphers, because this form is processed before the configuration file is read and any ENGINEs loaded. Use the \fBlist\fR command to get a list of supported ciphers. .PP Engines which provide entirely new encryption algorithms (such as the ccgost engine which provides gost89 algorithm) should be configured in the configuration file. Engines specified on the command line using \-engine options can only be used for hardware-assisted implementations of ciphers which are supported by the OpenSSL core or another engine specified in the configuration file. .PP When the enc command lists supported ciphers, ciphers provided by engines, specified in the configuration files are listed too. .PP A password will be prompted for to derive the key and \s-1IV\s0 if necessary. .PP The \fB\-salt\fR option should \fB\s-1ALWAYS\s0\fR be used if the key is being derived from a password unless you want compatibility with previous versions of OpenSSL. .PP Without the \fB\-salt\fR option it is possible to perform efficient dictionary attacks on the password and to attack stream cipher encrypted data. The reason for this is that without the salt the same password always generates the same encryption key. When the salt is being used the first eight bytes of the encrypted data are reserved for the salt: it is generated at random when encrypting a file and read from the encrypted file when it is decrypted. .PP Some of the ciphers do not have large keys and others have security implications if not used correctly. A beginner is advised to just use a strong block cipher, such as \s-1AES,\s0 in \s-1CBC\s0 mode. .PP All the block ciphers normally use PKCS#5 padding, also known as standard block padding. This allows a rudimentary integrity or password check to be performed. However, since the chance of random data passing the test is better than 1 in 256 it isn't a very good test. .PP If padding is disabled then the input data must be a multiple of the cipher block length. .PP All \s-1RC2\s0 ciphers have the same key and effective key length. .PP Blowfish and \s-1RC5\s0 algorithms use a 128 bit key. .SH "SUPPORTED CIPHERS" .IX Header "SUPPORTED CIPHERS" Note that some of these ciphers can be disabled at compile time and some are available only if an appropriate engine is configured in the configuration file. The output of the \fBenc\fR command run with the \fB\-ciphers\fR option (that is \fBopenssl enc \-ciphers\fR) produces a list of ciphers, supported by your version of OpenSSL, including ones provided by configured engines. .PP The \fBenc\fR program does not support authenticated encryption modes like \s-1CCM\s0 and \s-1GCM,\s0 and will not support such modes in the future. The \fBenc\fR interface by necessity must begin streaming output (e.g., to standard output when \fB\-out\fR is not used) before the authentication tag could be validated, leading to the usage of \fBenc\fR in pipelines that begin processing untrusted data and are not capable of rolling back upon authentication failure. The \s-1AEAD\s0 modes currently in common use also suffer from catastrophic failure of confidentiality and/or integrity upon reuse of key/iv/nonce, and since \fBenc\fR places the entire burden of key/iv/nonce management upon the user, the risk of exposing \s-1AEAD\s0 modes is too great to allow. These key/iv/nonce management issues also affect other modes currently exposed in \fBenc\fR, but the failure modes are less extreme in these cases, and the functionality cannot be removed with a stable release branch. For bulk encryption of data, whether using authenticated encryption modes or other modes, \fIcms\fR\|(1) is recommended, as it provides a standard data format and performs the needed key/iv/nonce management. .PP .Vb 1 \& base64 Base 64 \& \& bf\-cbc Blowfish in CBC mode \& bf Alias for bf\-cbc \& blowfish Alias for bf\-cbc \& bf\-cfb Blowfish in CFB mode \& bf\-ecb Blowfish in ECB mode \&
