NAME

       tpm2_rsadecrypt -  performs  RSA decryption using the indicated padding scheme according to IETF RFC 3447
       (PKCS#1). The scheme of keyHandle should not  be  TPM_ALG_NULL.   The  key  referenced  by  keyHandle  is
       required to be an RSA key (TPM_RC_KEY) with the decrypt attribute SET (TPM_RC_ATTRIBUTES).

SYNOPSIS

       tpm2_rsadecrypt[        COMMON        OPTIONS        ]        [        TCTI       OPTIONS       ]       [
       --keyHandle|--keyContext|--pwdk|--inFile|--outFile|--passwdInHex| ]

       performs RSA decryption using the indicated padding scheme according  to  IETF  RFC  3447  (PKCS#1).  The
       scheme of keyHandle should not be TPM_ALG_NULL.  The key referenced by keyHandle is required to be an RSA
       key (TPM_RC_KEY) with the decrypt attribute SET (TPM_RC_ATTRIBUTES).

DESCRIPTION

       tpm2_rsadecrypt performs RSA decryption using the indicated padding scheme according  to  IETF  RFC  3447
       (PKCS#1).  The  scheme  of  keyHandle  should  not  be  TPM_ALG_NULL.  The key referenced by keyHandle is
       required to be an RSA key (TPM_RC_KEY) with the decrypt attribute SET (TPM_RC_ATTRIBUTES).

OPTIONS

       -k ,--keyHandle
              the public portion of RSA key to use for  decryption

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

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

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

       -o ,--outFile
              Output file path, record the decrypted 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.

       -v, --version
              Display version information for this tool.

       -V, --verbose
              Increase the information that the tool prints to the console during its execution.

       [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.
