SoftHSM is an implementation of a cryptographic
store accessible through a PKCS#11 interface. You
can use it to explore PKCS#11 without having a
Hardware Security Module. It is being developed as
a part of the OpenDNSSEC project. SoftHSM uses
Botan for its cryptographic operations.

/usr/local, /etc, and /var are used by default. The performance of creating keys was improved. An error message is logged if the database cannot be opened. There is a known bug in which a version of Botan available in some OSes has a problem with the entropy. This causes SoftHSM to freeze in some operations. This problem can be worked around by upgrading to Botan 1.8.5 or greater.
