An encryption algorithm's security is boolean - it either leaks data to third parties or it doesn't. The algorithms we use are currently not known to be compromised, but lack of proof of compromise is not proof of lack of compromise. If the NSA has found a vulnerability in AES-256 or some mathematical breakthrough that makes it possible to decrypt AES-256-encrypted data in polynomial time, or even just a side-channel attack in $POPULAR_SSL_LIBRARY, all bets are off.
