SYNOPSIS

       tpm2_encryptdecrypt[     COMMON     OPTIONS     ]     [     TCTI     OPTIONS      ]      [
       --keyHandle|--keyContext|--pwdk|--decrypt|--inFile|--outFile|--passwdInHex| ]

       performs  symmetric encryption or decryption. keyHandle shall reference a symmetric cipher
       object.

DESCRIPTION

       tpm2_encryptdecrypt performs symmetric encryption or decryption. keyHandle shall reference
       a symmetric cipher object.

OPTIONS

       -k ,--keyHandle

       -c ,--keyContext
              filename of the key context used for the  operation

       -P ,--pwdk
              the password of key, optional

       -D ,--decrypt
              the  operation type, default NO, optional  YES the operation is decryption   NO the
              operation is encryption

       -I ,--inFile
              Input file path, containing the data to be  operated

       -o ,--outFile
              Output file path, record the operated data

       -X ,--passwdInHex
              passwords given by any options are hex format.

       [COMMON OPTIONS ]
              This collection of options are common to many programs and provide information that
              many users may expect.

       -h, --help
              Display a manual describing the tool and its usage.

       [TCTI OPTIONS ]
              This collection of options are used to configure the varous TCTI modules available.

       -T, --tcti
              Select  the TCTI used for communication with the next component down the TSS stack.
              In most configurations this will be the TPM but it could be a simulator  or  proxy.
              Supported TCTIs are or “device” or “socket” .

       -d, --device-file
              Specify the TPM device file for use by the device TCTI. The default is /dev/tpm0.

       -R, --socket-address
              Specify  the  domain  name  or  IP  address used by the socket TCTI. The default is
              127.0.0.1.

       -p, --socket-port
              Specify the port number used by the socket TCTI. The default is 2321.

       ENVIRONMENT: TCTI
              This collection of environment variables that may be used to configure  the  varous
              TCTI  modules  available.   The  values  passed  through  these  variables  can  be
              overridden on a per-command basis using the available command line options.

       TPM2TOOLS_TCTI_NAME
              Select the TCTI used for communication with the next component down the TSS  stack.
              In  most  configurations this will be the TPM but it could be a simulator or proxy.
              See 'OPTIONS' section for the names of supported TCTIs.

       TPM2TOOLS_DEVICE_FILE
              Specify the TPM device file for use by the device TCTI.

       TPM2TOOLS_SOCKET_ADDRESS
              Specify the domain name or IP address used by the socket TCTI.

       TPM2TOOLS_SOCKET_PORT
              Specify the port number used by the socket TCTI.
