tss2_decrypt(1)		    General Commands Manual	       tss2_decrypt(1)

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  parame-
       ters for	all keys and operations	of a specific TPM interaction like the
       name hash algorithm, the	asymmetric signature algorithm,	scheme and pa-
       rameters	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 cryp-
       tographic 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  re-
	 quested,  the	tool  will  provide errors from	man on stderr.	If the
	 "no-man" option if specified, or the manpager fails,  the  short  op-
	 tions 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.
