NAME¶

tpm2_rsaencrypt - performs RSA encryption using the indicated padding scheme according to IETF RFC 3447. 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_rsaencrypt[ COMMON OPTIONS ] [ TCTI OPTIONS ] [ --keyHandle|--keyContext|--inFile|--outFile| ]

performs RSA encryption using the indicated padding scheme according to IETF RFC 3447. 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_rsaencrypt performs RSA encryption using the indicated padding scheme according to IETF RFC 3447. 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 encryption

-c ,--keyContext

filename of the key context used for the operation

-I ,--inFile

Input file path, containing the data to be encrypted

-o ,--outFile

Output file path, record the encrypted data

[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.
