There are implementation details that could make the data recoverable even when RSA is used. The data itself is typically encrypted using a symmetric cipher (e.g. AES) and the key used for it would be encrypted using RSA. However, if the key for the symmetric algorithm was generated in a predictable way (e.g. using a pseudo-RNG initialized from the system time), it could be possible to bruteforce it in reasonable time.
