* Threading consideration (safety, usability) in API and plugins
* finish API:
pkey: ability to choose sign algorithm
pkey: ability to choose cipher for toDER/PEM passphrase
cert: Distinguished Names (Botan has X509_DN)
cert: get signature algorithm
cert: constraints, ex_constraints, policies, pathLimit, isCA, isSelfSigned
crl: add functions

pre-padded last block.

pkey: ability to choose cipher for toDER/PEM passphrase ?
- botan doesn't seem to allow this, but kiko wanted it...
* qt 4 upgrade:
new include styles
