NAME
       openssl-skeyutl - opaque symmetric keys routines


SYNOPSIS
       openssl skeyutl [-help] [-cipher cipher] [-skeymgmt skeymgmt] [-skeyopt opt:value] [-genkey] [-provider
       name] [-provider-path path] [-provparam [name:]key=value] [-propquery propq]


DESCRIPTION
       Not all cipher implementations support keys as raw bytes. E.g. PKCS#11 tokens can store them internally
       without any option to get the raw byte representation.

       This tool is designed for managing opaque symmetric keys.


OPTIONS
       -help
           Print out a usage message.

       -cipher cipher
           The cipher to generate the key for.

       -skeymgmt skeymgmt
           Some  providers may support opaque symmetric keys objects. To use them, we need to know the skeymgmt.
           If not specified, the name of the cipher will be used.

           To find out the name of the suitable symmetric key management, please refer  to  the  output  of  the
           "openssl list -skey-managers" command.

       -skeyopt opt:value
           To  obtain  an  existing  opaque symmetric key or to generate a new one, key options are specified as
           opt:value. These options can't be used together with any options implying raw key either directly  or
           indirectly.

       -genkey
           Generate a new opaque key object.

       -provider name
       -provider-path path
       -provparam [name:]key=value
       -propquery propq
           See "Provider Options" in openssl(1), provider(7), and property(7).
