cmu generatekeypair
This function generates an asymmetric key pair on the token or HSM. An optional input filename can be used to specify a file from which mandatory and optional attributes are to be read.
For DSA key generation, the domain parameters (Prime, Subprime, and Base) are required, and must be provided either as part of the command, or as responses to interactive prompting. If one is provided at the command line, then all three must be provided in that manner. If none are provided at the command line, then all three are prompted for interactive entry.
You may not provide only one or two of the parameters at the command line. Providing just one or two domain parameters is considered an error, and the command halts with an error message.

| Argument(s) | Description |
|---|---|
| -base=<length> | Defines a base length for DSA key generation. |
| -curvetype=<value> | This optional parameter defines the name of a curve type for ECDSA keys. Enter values 1-5 (1-NISTP 192 / 2-NISTP 224 / 3-NISTP 256 / 4-NISTP 384 / 5-NISTP 521). |
| -decrypt=<0/1> |
Defines the decrypt setting for the private key in the newly generated key pair. It must be set to True or False (or 1 or 0), with False being the default. If this parameter is set to True, then the encrypt setting for the public key should also be set to True. NOTE An HSM is often configured such that no key can have multiple functions - see policy #10 on Partition Capabilities and Policies to choose that configuration option. Thus if decrypt is set True, then unwrap and sign would need to be False. |
| -derive=<0/1> | Set to True or False (or 1 or 0). Note that an HSM is typically configured such that functional key attributes cannot be changed, so attempting to change this attribute will be rejected by the HSM. |
| -encrypt=<0/1> | Defines the encrypt setting for the public key in the newly generated key pair. It must be set to True or False (or 1 or 0), with False being the default. If this parameter is set to True, then the decrypt setting for the private key should also be set to True.
NOTE An HSM is often configured such that no key can have multiple functions - see policy #10 on Partition Capabilities and Policies to choose that configuration option. Thus if encrypt is set True, then wrap and verify would need to be False. |
| -endDate=<YYYYMMDD> | Defines the endDate field for the newly generated keys. The format for the value is YYYYMMDD. |
| -extractable=<0/1> | Defines the extractable setting for the private key in the newly generated key pair. It must be set to True or False (or 1 or 0), with False being the default. |
| -id=<hex_ID> | Defines the ID field for the newly generated keys. It must be set to a big-endian hexadecimal integer value. |
| -inputFile=<filename> | Defines the name of a file from which to obtain additional parameter settings, one per line, of the form <name>=<value>. |
| -keygenmech=<1/2/3> |
Defines the RSA key generation mechanism to be used. Applies to Luna HSM Client 7.3.0 and earlier. For newer versions, use -mech. Valid Values: >1 -- PKCS >2 -- FIPS 186-3 Only Primes >3 -- FIPS 186-3 Auxiliary Primes |
| -keyType=<keytype> | Defines the type of asymmetric keys to generate. This parameter is not required if the key type can be established by the presence of other parameters. (e.g. If -modulusBits and/or -publicExponent parameters are specified, then -keyType=RSA is redundant). Currently, only RSA key pairs are supported. |
| -label=<label> | Defines a label to be applied to both of the newly generated keys. If a multiple word label is required, the label value must be enclosed within quotation marks. |
| -labelPrivate=<label> | Defines a label to apply to the private key from the newly generated key pair. |
| -labelPublic=<label> | Defines a label to apply to the public key from the newly generated key pair. |
| -mech=<mechanism> |
Defines the RSA key generation mechanism to be used (formerly "-keygenmech"). Applies to Luna HSM Client 7.4.0 and newer. For previous versions, use -keygenmech. Valid Values: >pkcs -- PKCS >prime -- FIPS 186-3 Only Primes >aux -- FIPS 186-3 Auxiliary Primes |
| -modifiable=<0/1> | Defines the modifiable setting for each of the keys in the key pair. It must be set to True or False (or 1 or 0). |
| -modulusBits=<length> | Defines the length in bits of the modulus value for the generation of RSA key pairs. It must be set to a value between 1024 and 4096 that is a multiple of 64 bits. If the HSM policy 12 "Allow non-FIPS algorithms" is set to "No", then RSA key size is limited to 2048 bits or 3072 bits. |
| -prime=<length> | Defines a prime length for DSA key generation. |
| -publicExponent=<value> |
Defines the public exponent value to use in the generation of RSA key pairs. Valid values: 3,17,65537. Only 65537 is allowed in FIPS mode. |
| -sign=<0/1> |
Defines the sign setting for the private key in the newly generated key pair. It must be set to True or False (or 1 or 0), with False being the default. If this parameter is set to True, then the verify setting for the public key should also be set to True. NOTE An HSM is often configured such that no key can have multiple functions - see policy #10 on Partition Capabilities and Policies to choose that configuration option. Thus if sign is set True, then unwrap and decrypt would need to be False. |
| -startDate=<YYYYMMDD> | Defines the startDate field for the newly generated keys. The format for the value is YYYYMMDD. |
| -subject=<hex_value> | Defines the subject field for the newly generated keys. It must be set to a big-endian hexadecimal integer value. The subject field is typically set to the DER encoding of the subject distinguished name for the key. |
| -subprime=<length> | Defines a subprime bits length for DSA key generation. |
| -unwrap=<0/1> |
Defines the unwrap setting for the private key in the newly generated key pair. It must be set to True or False (or 1 or 0), with False being the default. If this parameter is set to True, then the wrap setting for the public key should also be set to True. NOTE An HSM is often configured such that no key can have multiple functions - see policy #10 on Partition Capabilities and Policies to choose that configuration option. Thus if unwrap is set True, then decrypt and sign would need to be False. |
| -verify=<0/1> |
Defines the verify setting for the public key in the newly generated key pair. It must be set to True or False (or 1 or 0), with False being the default. If this parameter is set to True, then the sign setting for the private key should also be set to True. NOTE An HSM is often configured such that no key can have multiple functions - see policy #10 on Partition Capabilities and Policies to choose that configuration option. Thus if verify is set True, then encrypt and wrap would need to be False. |
| -wrap=<0/1> |
Defines the wrap setting for the public key in the newly generated key pair. It must be set to True or False (or 1 or 0), with False being the default. If this parameter is set to True, then the unwrap setting for the private key should also be set to True. NOTE An HSM is often configured such that no key can have multiple functions - see policy #10 on Partition Capabilities and Policies to choose that configuration option. Thus if wrap is set True, then encrypt and verify would need to be False. |
| Common | |
| -password=<password> | The password for the role accessing the current slot, with the current command. If this is not specified, it is prompted. |
| -ped=<PED_ID> | Specifies the PED ID for the registered Remote PED that will handle authentication for the current slot, with the current command. You must specify this parameter to use Remote PED authentication. |
| -slot=<slot#> | The slot to be acted upon, by the current command. If this is not specified, it is prompted. |
