 %global common_description %{expand:
+ChaCha is a stream cipher family created by Daniel J. Bernstein. The most common
+ChaCha variant is ChaCha20 (20 rounds). ChaCha20 is standardized in RFC 7539.
+
 This package provides implementations of three ChaCha versions:
 
- - ChaCha20 with a 64 bit nonce (can en/decrypt up to 2^64 * 64 bytes for one 
- key-nonce combination)
- - ChaCha20 with a 96 bit nonce (can en/decrypt up to 2^32 * 64 bytes ~ 256 GB 
- for one key-nonce combination)
- - XChaCha20 with a 192 bit nonce (can en/decrypt up to 2^64 * 64 bytes 
- for one key-nonce combination)
+ - ChaCha20 with a 64 bit nonce (can en/decrypt up to 2^64 * 64 bytes for one
+   key-nonce combination)
+ - ChaCha20 with a 96 bit nonce (can en/decrypt up to 2^32 * 64 bytes ~ 256 GB
+   for one key-nonce combination)
+ - XChaCha20 with a 192 bit nonce (can en/decrypt up to 2^64 * 64 bytes for one
+   key-nonce combination)
 
-Furthermore the chacha sub package implements ChaCha20/12 and ChaCha20/8. 
-These versions use 12 or 8 rounds instead of 20. But it's recommended to use 
-ChaCha20 (with 20 rounds) - it will be fast enough for almost all purposes.}
