The cryptoadm utility displays cryptographic provider information for a system, configures the mechanism policy for each provider, and installs or uninstalls a cryptographic provider. The cryptographic framework supports three types of providers: a user-level provider (a PKCS11 shared library), a kernel software provider (a loadable kernel software module), and a kernel hardware provider (a cryptographic hardware device).
For kernel software providers, the cryptoadm utility provides the unload subcommand. This subcommand instructs the kernel to unload a kernel software providers.
For the cryptographic framework's metaslot, the cryptoadm utility provides subcommands to enable and disable the metaslot's features, list metaslot's configuration, specify alternate persistent object storage, and configure the metaslot's mechanism policy.
Administrators will find it useful to use syslog facilities (see syslogd(1M) and logadm(1M)) to maintain the cryptographic subsystem. Logging can be especially useful under the following circumstances:
If kernel-level daemon is dead, all applications fail. You can learn this from syslog and use svcadm(1M) to restart the svc:/system/cryptosvc service.
If there are bad providers plugged into the framework, you can learn this from syslog and remove the bad providers from the framework.
With the exception of the subcommands or options listed below, the cryptoadm command needs to be run by a privileged user.
subcommand list, any options
The cryptoadm utility has the various combinations of subcommands and options shown below.
Display the list of installed providers.
Display the system-wide configuration for metaslot.
Display a list of mechanisms that can be used with the installed providers or metaslot. If a provider is specified, display the name of the specified provider and the mechanism list that can be used with that provider. If the metaslot keyword is specified, display the list of mechanisms that can be used with metaslot.
Display the mechanism policy (that is, which mechanisms are available and which are not) for the installed providers. Also display the provider feature policy or metaslot. If a provider is specified, display the name of the provider with the mechanism policy enforced on it only. If the metaslot keyword is specified, display the mechanism policy enforced on the metaslot.
Display details about the specified provider if a provider is specified. If the metaslot keyword is specified, display details about the metaslot.
For the various list subcommands described above (except for list -p), the -v (verbose) option provides details about providers, mechanisms and slots.
Disable the mechanisms or provider features specified for the provider. See OPERANDS for a description of mechanism, provider-feature, and the all keyword.
Disable the metaslot feature in the cryptographic framework or disable some of metaslot's features. If no operand is specified, this command disables the metaslot feature in the cryptographic framework. If a list of mechanisms is specified, disable mechanisms specified for metaslot. If all mechanisms are disabled for metaslot, the metaslot will be disabled. See OPERANDS for a description of mechanism. If the auto-key-migrate keyword is specified, it disables the migration of sensitive token objects to other slots even if it is necessary for performing crypto operations. See OPERANDS for a description of auto-key-migrate.
Enable the mechanisms or provider features specified for the provider. See OPERANDS for a description of mechanism, provider-feature, and the all keyword.
If no operand is specified, this command enables the metaslot feature in the cryptographic framework. If a list of mechanisms is specified, it enables only the list of specified mechanisms for metaslot. If token-label is specified, the specified token will be used as the persistent object store. If the slot-description is specified, the specified slot will be used as the persistent object store. If both the token-label and the slot-description are specified, the provider with the matching token label and slot description is used as the persistent object store. If the default-keystore keyword is specified, metaslot will use the default persistent object store. If the auto-key-migrate keyword is specified, sensitive token objects will automatically migrate to other slots as needed to complete certain crypto operations. See OPERANDS for a description of mechanism, token, slot, default-keystore, and auto-key-migrate.
Install a user-level provider into the system. The provider operand must be an absolute pathname of the corresponding shared library. If there are both 32–bit and 64–bit versions for a library, this command should be run once only with the path name containing $ISA. Note that $ISA is not a reference to an environment variable. Note also that $ISA must be quoted (with single quotes [for example, '$ISA']) or the $ must be escaped to keep it from being incorrectly expanded by the shell. The user-level framework expands $ISA to an empty string or an architecture-specific directory, for example, sparcv9.
The preferred way of installing a user-level provider is to build a package for the provider. For more information, see the Solaris Security for Developer's Guide.
Install a kernel software provider into the system. The provider should contain the base name only. The mechanism-list operand specifies the complete list of mechanisms to be supported by this provider.
The preferred way of installing a kernel software provider is to build a package for providers. For more information, see the Solaris Security for Developer's Guide.
Uninstall the specified provider and the associated mechanism policy from the system. This subcommand applies only to a user-level provider or a kernel software provider.
Unload the kernel software module specified by provider.
Private interfaces for use by smf(5), these must not be used directly.
Display the command usage.
A user-level provider (a PKCS11 shared library), a kernel software provider (a loadable kernel software module), or a kernel hardware provider (a cryptographic hardware device).
A valid value of the provider operand is one entry from the output of a command of the form: cryptoadm list. A provider operand for a user-level provider is an absolute pathname of the corresponding shared library. A provider operand for a kernel software provider contains a base name only. A provider operand for a kernel hardware provider is in a “name/number” form.
A comma separated list of one or more PKCS #11 mechanisms. A process for implementing a cryptographic operation as defined in PKCS #11 specification. You can substitute all for mechanism-list, to specify all mechanisms on a provider. See the discussion of the all keyword, below.
A cryptographic framework feature for the given provider. Currently only random is accepted as a feature. For a user-level provider, disabling the random feature makes the PKCS #11 routines C_GenerateRandom and C_SeedRandom unavailable from the provider. For a kernel provider, disabling the random feature prevents /dev/random from gathering random numbers from the provider.
The keyword all can be used with with the disable and enable subcommands to operate on all provider features.
The label of a token in one of the providers in the cryptographic framework.
A valid value of the token operand is an item displayed under “Token Label” from the output of the command cryptoadm list -v.
The description of a slot in one of the providers in the cryptographic framework.
A valid value of the slot operand is an item displayed under “Description” from the output of the command cryptoadm list -v.
The keyword default-keystore is valid only for metaslot. Specify this keyword to set the persistent object store for metaslot back to using the default store.
The keyword auto-key-migrate is valid only for metaslot. Specify this keyword to configure whether metaslot is allowed to move sensitive token objects from the token object slot to other slots for performing cryptographic operations.
The keyword all can be used in two ways with the disable and enable subcommands:
You can substitute all for mechanism=mechanism-list, as in:
# cryptoadm enable provider=dca/0 all
This command enables the mechanisms on the provider and any other provider-features, such as random. You can also use all as an argument to mechanism, as in:
# cryptoadm enable provider=des mechanism=all
...which enables all mechanisms on the provider, but enables no other provider–features, such as random.

Solaris Security for Developer's Guide
If a hardware provider's policy was made explicitly (that is, some of its mechanisms were disabled) and the hardware provider has been detached, the policy of this hardware provider is still listed.
cryptoadm assumes that, minimally, a 32–bit shared object is delivered for each user-level provider. If both a 32–bit and 64–bit shared object are delivered, the two versions must provide the same functionality. The same mechanism policy applies to both.
