Frequently Asked Questions

What makes AES-256 encryption so secure?
AES-256 uses a 256-bit key, creating 2^256 possible combinations. This number is so large that brute-forcing the encryption is practically impossible with any existing or foreseeable technology.
Is AES-256 the same encryption used by the government?
Yes, AES-256 is approved by the U.S. National Security Agency (NSA) for protecting TOP SECRET classified information.
Can all ZIP software open AES-256 encrypted files?
Most modern archive software supports AES-256, including 7-Zip, WinZip, and built-in tools in Windows 10/11 and macOS. Very old software may only support the weaker ZipCrypto.
Is AES-256 encryption secure for years to come?
AES-256 is considered quantum-resistant for most practical purposes and is expected to remain secure for decades. It's the gold standard for data protection.
