iOS uses the openssl library, android uses Java's Security javax.cipher library. Both use RSA and encrypt/decrypt, but iOS is unable to decipher from android encrypted messages. No clear error is given except:

Decrypt error: error:0407A079:rsa routines:func(122):reason(121) ((null))

Android messages work when decrypted on the site.

So it's not technically feasible for us to respond to government warrants for the extraction of this data from devices in their possession running iOS 8."
