+A transform based on the NaCl
+.B crypto_secretbox
+transformation.
+The main difference is that NaCl uses XSalsa20,
+while TrIPE uses plain Salsa20 or ChaCha,
+because it doesn't need the larger nonce space.
+You can set the
+.B cipher
+key attribute to one of
+.BR salsa20 ,
+.BR salsa20/12 ,
+.BR salsa20/8 ,
+.BR chacha20 ,
+.BR chacha12 ,
+or
+.B chacha8
+to select the main cipher.
+You can set the
+.B mac
+key attribute to
+.B poly1305
+or
+.B poly1305/128
+but these are the default and no other choice is permitted.
+(This is for forward compatibility,
