How to List Available Providers

The Solaris Cryptographic Framework provides algorithms for several types of consumers:

User-level providers provide a PKCS #11 cryptographic interface to applications that are linked with the libpkcs11 library
Kernel software providers provide algorithms for IPsec, Kerberos, and other Solaris kernel components
Kernel hardware providers provide algorithms that are available to kernel consumers and to applications through the pkcs11_kernel library

List the providers in a brief format.

Note –

The contents and format of the providers list varies for different Solaris releases. Run the cryptoadm list command on your system to see the providers that your system supports.

Only those mechanisms at the user level are available for use by regular users.

% cryptoadm list
user-level providers:
    /usr/lib/security/$ISA/pkcs11_kernel.so
    /usr/lib/security/$ISA/pkcs11_softtoken.so

kernel software providers:
    des
    aes
    blowfish
    arcfour
    sha1
    md5
    rsa

kernel hardware providers:
    ncp/0

List the providers and their mechanisms in the Solaris Cryptographic Framework.

All mechanisms are listed in the following output. However, some of the listed mechanisms might be unavailable for use. To list only the mechanisms that the administrator has approved for use, see Example 14–16.

The output is reformatted for display purposes.

% cryptoadm list -m

Example 14–15 Finding the Existing Cryptographic Mechanisms

In the following example, all mechanisms that the user-level library, pkcs11_softtoken, offers are listed.

% cryptoadm list -m provider=/usr/lib/security/\$ISA/pkcs11_softtoken.so
Mechanisms:
CKM_DES_CBC,CKM_DES_CBC_PAD,CKM_DES_ECB,CKM_DES_KEY_GEN,
CKM_DES3_CBC,CKM_DES3_CBC_PAD,CKM_DES3_ECB,CKM_DES3_KEY_GEN,
…
CKM_SSL3_KEY_AND_MAC_DERIVE,CKM_TLS_KEY_AND_MAC_DERIVE

Example 14–16 Finding the Available Cryptographic Mechanisms

Policy determines which mechanisms are available for use. The administrator sets the policy. An administrator can choose to disable mechanisms from a particular provider. The -p option displays the list of mechanisms that are permitted by the policy that the administrator has set.

% cryptoadm list -p
user-level providers:
=====================
/usr/lib/security/$ISA/pkcs11_kernel.so: all mechanisms are enabled.
random is enabled.
/usr/lib/security/$ISA/pkcs11_softtoken.so: all mechanisms are enabled.
random is enabled.

kernel software providers:
==========================
des: all mechanisms are enabled.
aes: all mechanisms are enabled.
blowfish: all mechanisms are enabled.
arcfour: all mechanisms are enabled.
sha1: all mechanisms are enabled.
md5: all mechanisms are enabled.
rsa: all mechanisms are enabled.
swrand: random is enabled.

kernel hardware providers:
==========================
ncp/0: all mechanisms are enabled.
