<h3><a name="OPTIONS">OPTIONS</a></h3>
<p>The following options are used by the cryptography commands.</p>
<br>
<h4>Cryptographic Options</h4>
<dl>
<dt><a name="-cipher"><strong>-cipher</strong> <em>name</em></a></dt>
<dd>Name of cryptographic cipher to use. Used by encrypt/decrypt command
and CMAC & GMAC hash algorithms. For CMAC it must be one of AES-128-CBC,
AES-192-CBC, AES-256-CBC or DES-EDE3-CBC. For GMAC it should be a GCM mode
cipher e.g. AES-128-GCM. See <a href="#tls::ciphers"><b>tls::ciphers</b></a>
for the valid values.</dd>
</dl>
<dl>
<dt><a name="-digest"><strong>-digest</strong> <em>name</em></a></dt>
<dd>Name of hash function (aka message digest) to use.
See <a href="#tls::digests"><b>tls::digests</b></a> for the valid values.</dd>
</dl>
<dl>
<dt><a name="-iterations"><strong>-iterations</strong> <em>count</em></a></dt>
<dd>Number (integer > 0) of iterations to use in deriving the encryption
key. Default is 2048. Some <a href="#KDF"><b>KDF</b></a> implementations
require an iteration count.</dd>
</dl>
<dl>
<dt><a name="-iv"><strong>-iv</strong> <em>string</em></a></dt>
<dd>Initialization vector (IV) to use. Required for some ciphers and GMAC.
Cipher modes CBC, CFB, and OFB all need an IV while ECB and CTR modes do not.
A new, random IV should be created for each use. Think of the IV as a nonce
(number used once), it's public but random and unpredictable. See the
<a href="#tls::cipher"><b>tls::cipher</b></a> for iv_length and
when required (length > 0). Max is 16 bytes. If not set, it will default to \x00 fill data.</dd>
</dl>
<dl>
<dt><a name="-key"><strong>-key</strong> <em>string</em></a></dt>
<dd>Encryption key to use for cryptography function. Can be a binary or
text string. Longer keys provide better protection. Used by ciphers, HMAC,
some CMAC, and some KDF implementations. If the length of the key is <
<b>key_length</b> it will be padded. Max is 64 bytes. If > key_length, it will be rejected.
See the <a href="#tls::cipher"><b>tls::cipher</b></a> for key_length.</dd>
</dl>
<dl>
<dt><a name="-mac"><strong>-mac</strong> <em>name</em></a></dt>
<dd>Name of Message Authentication Code (MAC) to use.
See <a href="#tls::mac"><b>tls::macs</b></a> for the valid values.</dd>
</dl>
<dl>
<dt><a name="-password"><strong>-password</strong> <em>string</em></a></dt>
<dd>Password to use for some KDF functions. If not specified, the default
value is used. Can be a binary or text string.</dd>
</dl>
<dl>
<dt><a name="-properties"><strong>-properties</strong> <em>list</em></a></dt>
<dd>List of additional properties to pass to cryptographic function.</dd>
</dl>
<dl>
<dt><a name="-salt"><strong>-salt</strong> <em>string</em></a></dt>
<dd>Specifies salt value to use when encrypting data. Can be a binary or
text string. Default is to use a randomly generated value. This option is
used by BLAKE2 MAC and some KDF implementations use a non-secret unique
cryptographic salt.</dd>
<dt><a name="-size"><strong>-size</strong> <em>number</em></a></dt>
<dd>Set the output hash size in bytes. Used by KMAC128 or KMAC256 to specify
an output length. The default sizes are 32 or 64 bytes respectively.</dd>
</dl>
<dl>
<dt><a name="-xof"><strong>-xof</strong> <em>boolean</em></a></dt>
<dd>Set whether to use XOF. This option is used by KMAC.</dd>

<blockquote><table>
<tr><td><b>-N</b></td><td>The CPU/Memory cost parameter
must be larger than 1, a power of 2, and less than
2^(128 * r / 8). Default is 1048576.<td></tr>
<tr><td><b>-r</b></td><td>The blockSize parameter specifies the
block size. Must be greater than 0. Default is 8.<td></tr>
<tr><td><b>-p</b></td><td>The parallelization parameter
must be a positive integer less than or equal
