I have thought a bit more about how to integrate WebWorker/Multithreading support gracefully into OpenPGP.js. Here's my suggestion:
1. We create a "wrapper" for the web worker code in 'src/ciphers/openpgp.crypto.worker.js' 2. This file gets a dependeny to the synchronous symmetric entryption logic currently in 'src/ciphers/openpgp.crypto.sym.js' (see webworker branch). 3. We add an additional (optional) asynchronous callback to the place that usually invokes 'openpgp_crypto_symmetricEncrypt' and 'openpgp_crypto_symmetricDecrypt'. In that place, we check for WebWorker support and 'if(window.Worker)' we invoke 'src/ciphers/openpgp.crypto.worker.js' else we invoke the symmetric crypto in 'src/ciphers/openpgp.crypto.sym.js' as usual. Only that the values will be returned through the "asynchronous" callback rather than through return. If the optional callback is not defined by the caller, we return the synchronous/blocking symmetric crypto as usual. This approach would not break the current public API of openpgp.js, but rather add optional multithreading support. I think it would be better to do it this way than refactor the API for only asynchronous style, since it's easier to get started using the librara if it's synchronous by default. Also most applications such as simple email encryption will not require multithreading. Carsten, Sean... I am currently not familiar enough with the code to know where 3. should take place.
