+ <p>
+ This chapter describes the new api to encryption and decryption.
+ </p>
+
+ <section>
+ <title>Background</title>
+ <p>The CRYPTO app has evolved during its lifetime. Since also the OpenSSL cryptolib has changed the
+ API several times, there are parts of the CRYPTO app that uses a very old one internally and
+ other parts that uses the latest one. The internal definitions of e.g cipher names was a bit hard
+ to maintain.
+ </p>
+ <p>It turned out that using the old api in the new way (more about that later), and still keep it
+ backwards compatible, was not possible. Specially as more precision in the error messages was wanted
+ it could not be combined with the old standard.
+ </p>
+ <p>Therefore the old api (see next section) is kept for now but internally implemented with new primitives.
+ </p>
+ </section>
+
+ <section>
+ <title>The old API</title>
+ <p>The old functions - not recommended for new programs - are:</p>
+ <list>
+ <item><seealso marker="crypto#block_encrypt-3">block_encrypt/3</seealso></item>

+ <item><seealso marker="crypto#supports-0">supports/0</seealso></item>
+ </list>
+ <p>They are not deprecated for now, but may be in a future release.
+ </p>
+ </section>
+
+ <section>
+ <title>The new API</title>
+ <p>The new functions for encrypting or decrypting one single binary are:
+ </p>
+ <list>
+ <item><seealso marker="crypto#crypto_one_time/4">crypto_one_time/4</seealso></item>
+ <item><seealso marker="crypto#crypto_one_time/5">crypto_one_time/5</seealso></item>
+ <item><seealso marker="crypto#crypto_one_time_aead/6">crypto_one_time_aead/6</seealso></item>
+ <item><seealso marker="crypto#crypto_one_time_aead/7">crypto_one_time_aead/7</seealso></item>
+ </list>
+ <p>In those functions the internal crypto state is first created and initialized
+ with the cipher type, the key and possibly other data. Then the single binary is encrypted
+ or decrypted,
+ the crypto state is de-allocated and the result of the crypto operation is returned.
+ </p>
+ <p>The <c>crypto_one_time_aead</c> functions are for the ciphers of mode <c>ccm</c> or
+ <c>gcm</c>, and for the cipher <c>chacha20-poly1305</c>.
+ </p>
+ <p>For repeated encryption or decryption of a text divided in parts, where the internal
+ crypto state is initialized once, and then many binaries are encrypted or decrypted with
+ the same state, the functions are:
+ </p>
+ <list>
+ <item><seealso marker="crypto#crypto_init/4">crypto_init/4</seealso></item>
+ <item><seealso marker="crypto#crypto_init/3">crypto_init/3</seealso></item>
+ <item><seealso marker="crypto#crypto_update/2">crypto_update/2</seealso></item>
+ </list>
+ <p>The <c>crypto_init</c> initialies an internal cipher state, and one or more calls of
+ <c>crypto_update</c> does the acual encryption or decryption. Note that AEAD ciphers
+ can't be handled this way due to their nature.
+ </p>
+ <p>For repeated encryption or decryption of a text divided in parts where the
+ same cipher and same key is used, but a new initialization vector (nounce) should be applied
+ for each part, the functions are:
+ </p>
+ <list>
+ <item><seealso marker="crypto#crypto_dyn_iv_init/3">crypto_dyn_iv_init/3</seealso></item>
+ <item><seealso marker="crypto#crypto_dyn_iv_update/3">crypto_dyn_iv_update/3</seealso></item>
+ </list>
+ <p>An example of where those functions are needed, is when handling the TLS protocol.</p>
+ <p>For information about available algorithms, use:
+ </p>

+ <title>Examples of crypto_init/4 and crypto_update/2</title>
+ <p>The functions <seealso marker="crypto#crypto_init/4">crypto_init/4</seealso>
+ and <seealso marker="crypto#crypto_update/2">crypto_update/2</seealso> are intended
+ to be used for encrypting or decrypting a sequence of blocks. First one call of
+ <c>crypto_init/4</c> initialises the crypto context. One or more calls <c>crypto_update/2</c>
+ does the actual encryption or decryption for each block.
+ </p>
+ <p>This example shows first the encryption of two blocks and then decryptions of the cipher
+ text, but divided into three blocks just to show that it is possible to divide the plain text and
+ cipher text differently for some ciphers:</p>
+ <code type="erl">
+ 1> crypto:start().
+ ok
+ 2> Key = &lt;&lt;1:128>>.
+ &lt;&lt;0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1>>
+ 3> IV = &lt;&lt;0:128>>.
+ &lt;&lt;0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0>>
+ 4> StateEnc = crypto:crypto_init(aes_128_ctr, Key, IV, true). % encrypt -> true
+ #Ref&lt;0.3768901617.1128660993.124047>

+ #Ref&lt;0.3768901617.1128660994.124255>
+ 8> crypto:crypto_update(StateDec, &lt;&lt;67,44,216,166,25,130,203>>).
+ &lt;&lt;"First b">>
+ 9> crypto:crypto_update(StateDec, &lt;&lt;5,66,6,162,16,79,94,115,234,197,

+ &lt;&lt;"ytesSecond byte">>
+ 10> crypto:crypto_update(StateDec, &lt;&lt;41>>).
+ &lt;&lt;"s">>
+ 11>
+ </code>
+ <p>Note that the internal data that the <c>StateEnc</c> and <c>StateDec</c> references are
+ destructivly updated by the calls to <seealso marker="crypto#crypto_update/2">crypto_update/2</seealso>.
+ This is to gain time in the calls of the nifs interfacing the cryptolib. In a loop where the
+ state is saved in the loop's state, it also saves one update of the loop state per crypto operation.
+ </p>
+ <p>For example, a simple server receiving text parts to encrypt and send the result back to the
+ one who sent them (the <c>Requester</c>):
+ </p>
+ <code type="erl">
+ encode(Crypto, Key, IV) ->
+ crypto_loop(crypto:crypto_init(Crypto, Key, IV, true)).
+
+ crypto_loop(State) ->
+ receive
+ {Text, Requester} ->
+ Requester ! crypto:crypto_update(State, Text),
+ loop(State)
+ end.

+ <title>Retired cipher names</title>
+ <p>This table lists the retired cipher names in the first column and suggests names to replace them with
+ in the second column.
+ </p>
+ <p>The new names follows the OpenSSL libcrypto names. The format is ALGORITM_KEYSIZE_MODE.
+ </p>
+ <p>Examples of algorithms are aes, chacha20 and des. The keysize is the number of bits
+ and examples of the mode are cbc, ctr and gcm. The mode may be followed by a number depending
+ on the mode. An example is the ccm mode which has a variant called ccm8 where the so called tag
+ has a length of eight bits.
+ </p>
+ <p>The old names had by time lost any common naming which the new names now introduces. The new names include
+ the key length which improves the error checking in the lower levels of the crypto application.
