I started to port a light version of my Encryption application, DocuArmor, from the Windows 7 platform to the Android platform (minimum API 7). I've been able to load an existing PKCS12 keystore, encrypt and decrypt files on their emulator for API level 7 and above. I'm trying to determine if it's capable of allowing the creation of a keystore and it seems to fail on the creation of a certificate. It appears there are classes missing in their Java support. I receive an exception during the initialization of the BCStyle class or the PKCSObjectIdentifiers class with a java.lang.NoSuchFieldError. Is there any document that states what level of Bouncy Castle (BC) libraries are compatible with Android? I'm currently using BC ver 1.46. It appears that even though Android offers BC as a provider, it trimmed off some of the functions such as Certificate generation and manipulation. Is there any information on what functions are available under Android? Thanks.

Sorry, no idea on this one. I have heard that Android has recently updated to 1.45 so I can imagine there would be issues with 1.46. This is really a question best asked to someone at Google.

David,
I've browsed the threads on Google and unfortunately, they don't offer alot of details.

However, I was able to access the BouncyCastle provider under the emulator and execute the getInfo() method to print out the version. The results were Android ver 2.2 (API level 8) and below use BouncyCastle library 1.34. Android 2.3.1 (API Level 9) and above use BouncyCastle library 1.45.

I downgraded our DocuArmor suite from BouncyCastle ver 1.46 to 1.45 in order to be compatible with our phone application. Thanks for the tip about BC 1.45 being on one of the Android versions.
