Which encryption method is used?

SimpleumSafe uses AES-256 for encryption

AES-256 (Advanced Encryption Standard with a key length of 256 bits) is arguably the best-researched encryption algorithm and has been considered secure since its inception. It is even approved for use in the highest security level “Top Secret” in the U.S. government approved. SimpleumSafe has an encryption core (Simpleum®Cryptor). Every security operation is performed in the cryptor. The keys are not available outside of the cryptor.

The fastest supercomputers would take longer than the current age of the universe to crack an AES-256 key through trial and error.

Understanding AES-256: The Gold Standard of Encryption


At a time when data breaches and cyberattacks have become all too common, protecting sensitive information has never been more critical. This is where AES-256 comes into play, a reliable and powerful encryption standard that has become the first choice for many seeking world-class data protection. This article explores the intricacies of AES-256 and why it is considered one of the most secure encryption methods.

AES-256 taken a closer look

  1. What is AES?

    • AES stands for Advanced Encryption Standard and is an encryption algorithm adopted by the US government in the early 2000s. It was developed to replace the outdated Data Encryption Standard (DES).

    • The algorithm is based on the Rijndael cipher designed by Belgian cryptographers Vincent Rijmen and Joan Daemen.

  2. The numbers game: understanding key lengths

    • The “256” in AES-256 denotes the key length of 256 bits. AES also supports other key lengths, namely 128 and 192 bits.
    • The key length plays a crucial role in the security of the encryption. The longer the key, the higher the number of possible combinations, which makes cracking much more difficult.

Why AES-256 stands out

  1. First-Class Security Due to its 256-bit key length, AES-256 offers a significantly large number of possible key combinations. To put that into perspective: The fastest supercomputers would take longer than the current age of the universe to crack an AES-256 key through trial and error.

  2. Resistance to Attacks AES-256 has passed extensive cryptanalytic testing and, when implemented correctly, remains resistant to all known practical attacks. This is proof of its robustness and reliability.

  3. Universal Application From secure communications and online banking to government data protection and cloud storage, AES-256 is used in a variety of applications to ensure data integrity and confidentiality across platforms.


AES-256 has rightly earned a reputation as one of the safest and most trusted encryption standards. It embodies the combination of cutting-edge cryptographic research with practical applicability. Whether you are a business protecting customer data or an individual protecting personal files, understanding and applying AES-256 is an essential step towards a more secure digital landscape.
