 == Post quantum cryptography
 
-Quantum computers are here and getting more power in available qubits each year. Quantum computers are and will be capable of decrypting information that was encrypted with algorithms that were thought to be safe. For some years now, a lot of encrypted communicatation using quantum vulnerable cryptoraphy is being recorded. This information will be decrypted when the quantum computers are powerful enough. Even tough the information may be old, it still could contain valuable information that can be misused. Besides the fact that some private information will be known to parties it was not intended for.

 SQL injections can occur, when unfiltered data from the client, e.g. the input of a search field, gets into the SQL interpreter of the application itself.
