| 36 // WebCrypto operations can be slow. For instance generating an RSA key can | |
| 37 // seconds. | |
| 38 // | |
| 39 // Moreover the underlying crypto libraries are not threadsafe when operating | |
| 40 // on the same key. | |
| 41 // | |
| 42 // The strategy used here is to run a sequenced worker pool for all WebCrypto | |
| 43 // operations (except structured cloning). This same pool is also used by | |
| 44 // requests started from Blink Web Workers. | |
| 45 // | |
| 46 // A few notes to keep in mind: | |
| 47 // | |
| 48 // * PostTaskAndReply() cannot be used for two reasons: | |
| 49 // | |
| 50 // (1) Blink web worker threads do not have an associated message loop so | |
| 51 // construction of the reply callback will crash. | |
| 52 // | |
| 53 // (2) PostTaskAndReply() handles failure posting the reply by leaking the | |
| 54 // callback, rather than destroying it. In the case of Web Workers this | |
| 55 // condition is reachable via normal execution, since Web Workers can | |
| 56 // be stopped before the WebCrypto operation has finished. A policy of | |
| 57 // leaking would therefore be problematic. | |
| 58 // | |
| 59 // * blink::WebArrayBuffer is NOT threadsafe, and should therefore be allocated | |
| 60 // on the target Blink thread. | |
| 61 // | |
| 62 // TODO(eroman): Is there any way around this? Copying the result between | |
| 63 // threads is silly. | |
| 64 // | |
| 65 // * WebCryptoAlgorithm and WebCryptoKey are threadsafe (however the key's | |
| 66 // handle(), which wraps an NSS/OpenSSL type, may not be and should only be | |
| 67 // used from the webcrypto thread). | |
| 68 // | |
| 69 // * blink::WebCryptoResult is not threadsafe and should only be operated on | |
| 70 // the target Blink thread. HOWEVER, it is safe to delete it from any thread. | |
| 71 // This can happen if by the time the operation has completed in the crypto | |
| 72 // worker pool, the Blink worker thread that initiated the request is gone. | |
| 73 // Posting back to the origin thread will fail, and the WebCryptoResult will | |
| 74 // be deleted while running in the crypto worker pool. | |
