NSA Recommendations

The US government announced in June 2003 regarding the AES algorithm (following an NSA analysis):

« The architecture and length of all key sizes of the AES algorithm (128, 192 and 256) 
are sufficient to protect classified documents up to the “SECRET” level. 
The “TOP SECRET” level requires 192 or 256 bit keys. 
The implementation of AES in products intended for the protection of systems and/or documents related to national security 
must be subject to analysis and certification by the NSA before their acquisition and use »
