Is there a PHP lib that can generate Bitcoin privkeys+addresses, sign tx, etc?

There doesn't seem to be an actual Bitcoin implementation in PHP yet, right?

I know bitcoin-php from Mike Gogulski, which appears to wrap access to bitcoind (or did I miss something?). But I'm rather looking for a library that can generate private keys + addresses. So basically an implementation for secp256k1 ECDSA and base58 encoding.

Generating + signing transactions would be even better, although obviously this depends on the sending address' history data from the blockchain (thus requiring a bitcoind client or some online API).

Github.com/mdanter/phpecc is a great help for the elliptic curve stuff, but nothing I know of does the transaction creation.

I've written some stuff for generating deterministic address using it. Github.com/Bit-Wasp/multisig/blob/application/libraries
