NAME

       tss2_decrypt(1) - decrypts data

SYNOPSIS

       tss2_decrypt [OPTIONS]

SEE ALSO

       fapi-config(5)  to  adjust Fapi parameters like the used cryptographic profile and TCTI or
       directories for the Fapi metadata storages.

       fapi-profile(5) to determine the cryptographic algorithms and parameters for all keys  and
       operations  of  a  specific  TPM  interaction like the name hash algorithm, the asymmetric
       signature algorithm, scheme and parameters and PCR bank selection.

DESCRIPTION

       tss2_decrypt(1) - This command decrypts data that was encrypted using  tss2_encrypt  using
       the  TPM  decryption  schemes  as  specified  in  the  cryptographic  profile  (cf., fapi-
       profile(5)).

OPTIONS

       These are the available options:

       • -p, --keyPath=STRING:

         Identifies the decryption key.

       • -i, --cipherText=FILENAME or - (for stdin):

         The JSON-encoded cipherText.

       • -f, --force:

         Force Overwriting the output file.

       • -o, --plainText=FILENAME or - (for stdout):

         Returns the decrypted data.  Optional parameter.

COMMON OPTIONS

       This collection of options are common to all tss2 programs and  provide  information  that
       many users may expect.

       • -h,  --help  [man|no-man]: Display the tools manpage.  By default, it attempts to invoke
         the manpager for the tool, however, on failure will output a short tool  summary.   This
         is  the  same  behavior  if  the “man” option argument is specified, however if explicit
         “man” is requested, the tool will provide errors from man on stderr.   If  the  “no-man”
         option if specified, or the manpager fails, the short options will be output to stdout.

         To  successfully  use  the  manpages feature requires the manpages to be installed or on
         MANPATH, See man(1) for more details.

       • -v, --version: Display version information for this tool, supported tctis and exit.

EXAMPLE

                  tss2_decrypt --keyPath=HS/SRK/myRSACrypt --cipherText=cipherText.file --plainText=plainText.file

RETURNS

       0 on success or 1 on failure.
