- Fixed a bug in error return for <c>crypto:poly1305/2</c>.
- It returned the atom <c>notsup</c> instead of the
- exception <c>notsup</c>.</p>

- The cipher chacha20 was introduced in OpenSSL 1.1.0.
- However, it could in a very odd situation fail for
- versions less than OpenSSL 1.1.0d. It is therefore not
- available if the linked cryptolib is OpenSSL of version
- 1.1.0c or earlier.</p>

- <p> A new <c>rand</c> module algorithm, <c>exro928ss</c>
- (Xoroshiro928**), has been implemented. It has got a
- really long period and good statistical quality for all
- output bits, while still being only about 50% slower than
- the default algorithm. </p><p> The same generator is also
- used as a long period counter in a new <c>crypto</c>
- plugin for the <c>rand</c> module, algorithm
- <c>crypto_aes</c>. This plugin uses AES-256 to scramble
- the counter which buries any detectable statistical
- artifacts. Scrambling is done in chunks which are cached
- to get good amortized speed (about half of the default
- algorithm). </p>

- Crypto's single C-file is splitted into multiple files.
- The different coding styles in the different parts are
- unified into a single style.</p>

- Build configuration of the <c>crypto</c> application has
- been moved from the <c>erts</c> application into the
- <c>crypto</c> application.</p>

- Adds two hash functions blake2b and blake2s (64 bit hash
- and 32 bit hash respectively). These are modern and
- standard hash functions used in blockchains and encrypted
- communication protocols. The hash functions are available
- in OpenSSL since version 1.1.1.</p>

- A new API is implemented in crypto. So far it is not
- published but used for implementing the
- <c>crypto:block_*</c> and <c>crypto:stream_*</c>
- interfaces.</p>
- <p>
- Please note that since the error checking is more
- thorough, there might be arguments with faulty lengths
- that are no longer accepted.</p>

- maps with information about the hash or cipher in the
- argument.</p>
