#304
I'm interested to use chacha20-poly1305 to encrypt/decrypt files, yet it gives AEAD ciphers not supported

openssl enc -chacha20-poly1305 -in inputfile.txt -out encryptedfile.dat
enc: AEAD ciphers not supported
enc: Use -help for summary.

But I do see it in ciphers

Unfortunately to properly support AEAD ciphers in an enc utility would require a major effort. First we would have to design a new file format for that.
