NAME

       clevis-encrypt-http -- Encrypts using a REST HTTP escrow server policy

SYNOPSIS

       clevis encrypt http CONFIG < PT > JWE

OVERVIEW

       The  clevis encrypt http  command  encrypts using a REST HTTP escrow server policy.  Its only argument is
       the JSON configuration object.

       When using the HTTP pin, we create a new, cryptographically-strong, random key.  This key is stored in  a
       remote HTTP escrow server (using a simple PUT or POST).  Then at decryption time, we attempt to fetch the
       key back again in order to decrypt our data.  So, for our configuration we need to pass the  URL  to  the
       key location:

              $ clevis encrypt http '{"url":"https://escrow.srv/1234"}' < PT > JWE

       To decrypt the data, simply provide the ciphertext (JWE):

              $ clevis decrypt < JWE > PT

       Notice  that  we did not pass any configuration during decryption.  The decrypt command extracted the URL
       (and possibly other configuration) from the JWE object, fetched the encryption key from  the  escrow  and
       performed decryption.

CONFIG

       This command uses the following configuration properties:

       • url (string) : The URL where the key is stored (REQUIRED)

       • http (boolean) : Allow or disallow non-TLS HTTP (default: false)

       • type (string) : The type of key to store (default: octet-stream)

       • method (string) : The HTTP method to use (default: PUT)
