$ echo foo | clevis encrypt http '{ "url": "http://192.168.100.1:8888", "http": true, "type": "jwk+json" }' | clevis decrypt
Invalid key!
Usage: jose jwe dec -i JWE [-I CT] -k JWK [-p] [-O PT]

Decrypts a JWE using the supplied JWKs and outputs plaintext

  -i JSON --input=JSON     Parse JWE from JSON
  -i FILE --input=FILE     Read JWE from FILE
  -i -    --input=-        Read JWE from standard input

  -I FILE --detached=FILE  Read decoded ciphertext from FILE
  -I -    --detached=-     Read decoded ciphertext from standard input

  -p      --password       Prompt for a decryption password, if necessary

  -k FILE --key=FILE       Read JWK(Set) from FILE
  -k -    --key=-          Read JWK(Set) from standard input

  -O JSON --detach=JSON    Parse JWE from JSON
  -O FILE --detach=FILE    Read JWE from FILE
  -O -    --detach=-       Read JWE from standard input
                           Default: "-"

"octet-stream" works fine:

$ echo foo | clevis encrypt http '{ "url": "http://192.168.100.1:8888", "http": true, "type": "octet-stream" }' | clevis decrypt
foo

Hopefully fixed by https://github.com/latchset/clevis/pull/47
