If some of the cryptographic mechanisms from a library provider should not be used, you can remove selected mechanisms. This procedure uses the DES mechanisms in the pkcs11_softtoken library as an example.
Become superuser or assume a role that includes the Crypto Management rights profile.
To create a role that includes the Crypto Management rights profile and assign the role to a user, see Example 9–7.
List the mechanisms that are offered by a particular user-level software provider.
% cryptoadm list -m provider=/usr/lib/security/\$ISA/pkcs11_softtoken.so /usr/lib/security/$ISA/pkcs11_softtoken.so: 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_AES_CBC,CKM_AES_CBC_PAD,CKM_AES_ECB,CKM_AES_KEY_GEN, … |
List the mechanisms that are available for use.
$ cryptoadm list -p user-level providers: ===================== … /usr/lib/security/$ISA/pkcs11_softtoken.so: all mechanisms are enabled. random is enabled. … |
Disable the mechanisms that should not be used.
$ cryptoadm disable provider=/usr/lib/security/\$ISA/pkcs11_softtoken.so \ > mechanism=CKM_DES_CBC,CKM_DES_CBC_PAD,CKM_DES_ECB |
List the mechanisms that are available for use.
$ cryptoadm list -p provider=/usr/lib/security/\$ISA/pkcs11_softtoken.so /usr/lib/security/$ISA/pkcs11_softtoken.so: all mechanisms are enabled, except CKM_DES_ECB,CKM_DES_CBC_PAD,CKM_DES_CBC. random is enabled. |
In the following example, a disabled DES mechanism is again made available for use.
$ cryptoadm list -m provider=/usr/lib/security/\$ISA/pkcs11_softtoken.so /usr/lib/security/$ISA/pkcs11_softtoken.so: 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, … $ cryptoadm list -p provider=/usr/lib/security/\$ISA/pkcs11_softtoken.so /usr/lib/security/$ISA/pkcs11_softtoken.so: all mechanisms are enabled, except CKM_DES_ECB,CKM_DES_CBC_PAD,CKM_DES_CBC. random is enabled. $ cryptoadm enable provider=/usr/lib/security/\$ISA/pkcs11_softtoken.so \ > mechanism=CKM_DES_ECB $ cryptoadm list -p provider=/usr/lib/security/\$ISA/pkcs11_softtoken.so /usr/lib/security/$ISA/pkcs11_softtoken.so: all mechanisms are enabled, except CKM_DES_CBC_PAD,CKM_DES_CBC. random is enabled. |
In the following example, all mechanisms from the user-level library are enabled.
$ cryptoadm enable provider=/usr/lib/security/\$ISA/pkcs11_softtoken.so all $ cryptoadm list -p provider=/usr/lib/security/\$ISA/pkcs11_softtoken.so /usr/lib/security/$ISA/pkcs11_softtoken.so: all mechanisms are enabled. random is enabled. |
In the following example, the libpkcs11.so.1 library is removed.
$ cryptoadm uninstall provider=/opt/SUNWconn/lib/\$ISA/libpkcs11.so.1 $ cryptoadm list user-level providers: /usr/lib/security/$ISA/pkcs11_kernel.so /usr/lib/security/$ISA/pkcs11_softtoken.so kernel software providers: … |
