Hello Everyone, I just viewed the AeroGear-Crypto-iOS Library here : https://github.com/aerogear/aerogear-crypto-ios Can someone answer few of my questions: * What is the Algorithm being used for Encryption/Decryption?

* What is the Key Length used? (Can we use 1024?)

* What is the algorithm used for Digital Signature ?

Thanks & Regards,. Saravanan V _______________________________________________ aerogear-dev mailing list aerogear-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/aerogear-dev

For symmetric we currently use common crypto and CBC mode (see http://aerogear.org/docs/guides/iOSCookbook/#crypto) but we plan for the next release to go with NaCi lib (for a broader range of algorithms - GCM ) --> The GitHub sample does provide Asymmetric example. So, what is the Algorithm used for Asymmetric ?? > * What is the Key Length used? (Can we use 1024?) not yet --> "AGRandomGenerator" does provide an API to get random bytes. [AGRandomGenerator randomBytes:<length>]; So, does it mean that we could have the key in any size??

Hi my friend, sorry for the delay on it, but I was exactly writing about it (http://blog.abstractj.org/articles/AeroGear-iOS-crypto/). Answering your question, AGRandomGenerator is our wrapper to provide random bytes for salts and IVs, the minimum established is 16 bytes. For symmetric encryption you must stick to standards: 128, 192 and 256 bits, but as far as I can tell our default was set to 256 bits. I hope it helps otherwise feel free to ask. -- abstractj On February 21, 2014 at 6:43:28 AM, Saravanan V (saru2020(a)gmail.com) wrote: > > Hello Everyone, > > I just viewed the AeroGear-Crypto-iOS Library here : > https://github.com/aerogear/aerogear-crypto-ios > > Can someone answer few of my questions: > * What is the Algorithm being used for Encryption/Decryption? > * What is the Key Length used?
