| <h2>Apache jDKIM Project<a name="Apache_jDKIM_Project"></a></h2> |
| |
| <p> |
| jDKIM is a DKIM implementation library written in Java. |
| It provides both verification and signing and also |
| provides Mailets for the Apache JAMES project. |
| </p> |
| |
| |
| <p> |
| The 0.2 release is the first release. It requires Java 1.5 at |
| runtime and it requires the JVM running the library to support |
| SHA256withRSA cypher suite. The default Sun Java 1.5 does support this |
| suite. If your JVM doesn't support it you can install a third party |
| cryptography provider like BouncyCastle and configure it appropriately |
| in your JVM. |
| </p> |
| |
| |
| <p> |
| The architecture is thought to handle multiple signatures with |
| performance in mind: body hashing for multiple signatures is computed |
| concurrently in a single stream run. |
| </p> |
| |
| |
| <p> |
| The whole internal verification/signing is done via OutputStream |
| leaving much more flexibility than the use of InputStream. As the |
| InputStream approach is easier from the user side the default |
| implementation simply prepare the OutputStream and copy the supplied |
| InputStream to the OutputStream. |
| </p> |
| |
| |
| <p> |
| Please make sure you use dnsjava <b>2.0.7 or greater</b> |
| as 2.0.6 and previous versions don't handle correctly some TXT |
| record escaping that are very common in DKIM public key records. |
| Failure to include such an updated dnsjava will prevent jDKIM |
| from correctly verify signatures. |
| </p> |
| |
| |
| <p> |
| The product currently include a generic library module |
| called "main" and a module providing mailets for DKIM |
| signing |
