Enable debugging.
This option takes an integer number as its argument.
The value of
\f\*[I-Font]number\f[]
is constrained to being:
.in +4
.nf
.na
in the range  0 through 9999
.fi
.in -4
.sp
Specifies the debug level.
.TP
.NOP \f\*[B-Font]\-\-infile\f[]=\f\*[I-Font]file\f[]
Input file.
.sp
.TP
.NOP \f\*[B-Font]\-\-outfile\f[]=\f\*[I-Font]string\f[]
Output file.
.sp
.TP
.NOP \f\*[B-Font]\-\-generate\-rsa\f[]
Generate an RSA private-public key pair.
.sp
Generates an RSA private-public key pair in the TPM chip. 
The key may be stored in file system and protected by a PIN, or stored (registered)
in the TPM chip flash.
.TP
.NOP \f\*[B-Font]\-\-register\f[]
Any generated key will be registered in the TPM.
This option must appear in combination with the following options:
generate-rsa.
.sp
.TP
.NOP \f\*[B-Font]\-\-signing\f[]
Any generated key will be a signing key.
This option must appear in combination with the following options:
generate-rsa.
This option must not appear in combination with any of the following options:
legacy.
.sp
.TP
.NOP \f\*[B-Font]\-\-legacy\f[]
Any generated key will be a legacy key.
This option must appear in combination with the following options:
generate-rsa.
This option must not appear in combination with any of the following options:
signing.
.sp
.TP
.NOP \f\*[B-Font]\-\-user\f[]
Any registered key will be a user key.
This option must appear in combination with the following options:
register.
This option must not appear in combination with any of the following options:
system.
.sp
The generated key will be stored in a user specific persistent storage.
.TP
.NOP \f\*[B-Font]\-\-system\f[]
Any registered key will be a system key.
This option must appear in combination with the following options:
register.
This option must not appear in combination with any of the following options:
user.
.sp
The generated key will be stored in system persistent storage.
.TP
.NOP \f\*[B-Font]\-\-pubkey\f[]=\f\*[I-Font]url\f[]
Prints the public key of the provided key.
.sp
.TP
.NOP \f\*[B-Font]\-\-list\f[]
Lists all stored keys in the TPM.
.sp
.TP
.NOP \f\*[B-Font]\-\-delete\f[]=\f\*[I-Font]url\f[]
Delete the key identified by the given URL (UUID)..
.sp
.TP
.NOP \f\*[B-Font]\-\-test\-sign\f[]=\f\*[I-Font]url\f[]
Tests the signature operation of the provided object.
.sp
It can be used to test the correct operation of the signature operation.
This operation will sign and verify the signed data.
.TP
.NOP \f\*[B-Font]\-\-sec\-param\f[]=\f\*[I-Font]security\f[] \f\*[I-Font]parameter\f[]
Specify the security level [low, legacy, medium, high, ultra]..
.sp
This is alternative to the bits option. Note however that the
values allowed by the TPM chip are quantized and given values may be rounded up.
.TP
.NOP \f\*[B-Font]\-\-bits\f[]=\f\*[I-Font]number\f[]
Specify the number of bits for key generate.
This option takes an integer number as its argument.
.sp
.TP
.NOP \f\*[B-Font]\-\-inder\f[], \f\*[B-Font]\-\-no\-inder\f[]
Use the DER format for keys..
The \fIno\-inder\fP form will disable the option.
.sp
The input files will be assumed to be in the portable
DER format of TPM. The default format is a custom format used by various
TPM tools
.TP
.NOP \f\*[B-Font]\-\-outder\f[], \f\*[B-Font]\-\-no\-outder\f[]
Use DER format for output keys.
The \fIno\-outder\fP form will disable the option.
.sp
The output will be in the TPM portable DER format.
.TP
.NOP \f\*[B-Font]\-\-srk\-well\-known\f[]
SRK has well known password (20 bytes of zeros).
.sp
This option has not been fully documented.
.TP
.NOP \f\*[B-Font]\-h\f[], \f\*[B-Font]\-\-help\f[]
Display usage information and exit.
.TP
.NOP \f\*[B-Font]\-\&!\f[], \f\*[B-Font]\-\-more-help\f[]
Pass the extended usage information through a pager.
.TP
.NOP \f\*[B-Font]\-v\f[] [{\f\*[I-Font]v|c|n\f[] \f\*[B-Font]\-\-version\f[] [{\f\*[I-Font]v|c|n\f[]}]}]
Output version of program and exit.  The default mode is `v', a simple
version.  The `c' mode will print copyright information and `n' will
print the full copyright notice.
