Overview
Comment:Split list operations into separate functions to make it easier for OpenSSL 3.0 changes. Added pkey list function. Added mac info and pkey info placeholder functions. More checks for NULL pointers. Moved legacy load ciphers and digest to init routine.

Improved key and iv storage to use zero padded buffer to ensure no buffer overrun in OpenSSL API if string pointer is used. Added cipher default option for encrypt and decrypt. Pass data as last arg without -data option. check-in: 191f8b29bc user: bohagan tags: crypto

<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, OFB and CTR all need an IV while ECB mode does 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> command for iv size and
    when required.</dd>
   <a href="#tls::cipher"><b>tls::cipher</b></a> for iv_length and
    when required (length > 0). If not set, it will default to \x00 fill data.</dd>

<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. Key lengths less than <b>key_length</b>
    size may be padded or rejected. See the
    <a href="#tls::cipher"><b>tls::cipher</b></a> command for key size.</dd>
    some CMAC, and some KDF implementations. If the length of the key is &lt;
    <b>key_length</b> it will be padded. If &gt; key_length, it will be rejected.
    See the <a href="#tls::cipher"><b>tls::cipher</b></a> for key_length.</dd>
</dl>

	key_length, iv_length, type, and mode list. If block-size is 1,

    <dt><a name="tls::ciphers"><strong>tls::ciphers</strong>
    <em>?protocol? ?verbose? ?supported?</em></a></dt>
    <dd>Without any args, returns a list of all symmetric ciphers for use with
	the <a href="#-cipher"><b>-cipher</b></a> option. With <em>protocol</em>,
	only the ciphers supported for that protocol are returned. See
	<b>tls::protocols</b> command for the supported protocols. If
