CryptoEX library

[agraham]

The question is what do you want to achieve? As I'm doing this for fun I'm only prepared to get involved in supplying the low-level algorithms and functions that I can independently test and verify, like in my library. For anything further involving certificates and interactions then you are on your own and really need to consult a paid professional with security experience.

Version 1.3 now posted which has data signing and verification added to the RSA object.

At the request of LineCutter, which was the reason for posting this version, the source code is included in the zip so the library can be merged.

Thanks, again!

Version 1.4 now posted includes byte conversions to and from Base64 as well as encoded strings. The help has been clarified and the string encoding may now be specified - previously it assumed to always be UTF8.

The encryptions all round trip successfully but no guarantees for compatibility interworking with third party data as I can't try that.

As you saw in my previous question under byteconversion library, I'm trying to get a match between b4ppc app and b4a app on encryption.

I'm using the same key array in both apps.
In b4a there is an initialization vector which doesn't exist here.
Here there is mode, but neither made it the same.
Can you advise what has to be done (probably in the b4a app) to make it compatible ?
Thanks

Alternatively - maybe another encryption method will work better, can you recommend ?

edit: Hold it, I found IV in cryptoEx as well, I'll try to include it and check ...

Edit: Big success !, with mode 1 and using the same IV in both apps
