5 Best Free Online Rijndael Encryption Websites

Here is a list of best free online Rijndael encryption websites. Rijndael is a symmetric key encryption algorithm, which means the same secret key is used for both encryption and decryption algorithms. It is also a part of AES or Advanced Encryption Algorithms. The main advantage of Rijndael is its strong security that resists various cryptographic attacks. This algorithm is widely used to encrypt sensitive text data and files. If you also want to do that, then check out these online Rijndael encryption websites.

These websites can easily encrypt text messages and information using the Rijndael algorithm. However, only a few websites can encrypt files through this algorithm. Some of these websites also support multiple encryption modes like CBC (Cipher Block Chaining), CTR, CFB, ECB (Electronic Codebook), STREAM, and more. Before doing the encryption, users can also specify the encryption key and key size (128, 192, or 256 bits). I have also included the necessary data encryption steps in the description of each website. Apart from encryption, they can also be used to perform Rijndael decryption operations.

These websites have many additional tools like Whois, Email Verifier, DNS Record Viewer, JWS Parser, SSH-Keygen, Sign CSR, Generate HMAC, etc. Go through the list to learn more about these websites.

Frequently Asked Questions

What is Rijndael encryption method?

Rijndael is a symmetric key encryption algorithm, which means the same secret key is used for both encryption and decryption algorithms. It is also a part of AES or Advanced Encryption Algorithms. The main advantage of Rijndael is its strong security that resists various cryptographic attacks.

What is the difference between Rijndael and AES?

Rijndael and AES are closely related encryption algorithms, and the main difference between them lies in their key and block size options. Rijndael is a symmetric encryption algorithm designed by Vincent Rijmen and Joan Daemen. It supports a variety of block sizes and key sizes, including 128-bit, 192-bit, and 256-bit block sizes with key sizes of 128, 192, and 256 bits. Rijndael was the submission that won the NIST competition for the Advanced Encryption Standard (AES). On the other hand, AES is a subset of the Rijndael algorithm. AES specifically refers to Rijndael with a fixed block size of 128 bits and key sizes of 128, 192, or 256 bits. This means AES has three standard configurations: AES-128, AES-192, and AES-256.

What size key is Rijndael?

Rijndael, as an algorithm, supports multiple key sizes. When referring to Rijndael, it's essential to specify the key size you are using. Rijndael supports the following key sizes: 128 bits (16 bytes), 192 bits (24 bytes), 256 bits (32 bytes).

What is the Rijndael key schedule?

The Rijndael key schedule, often referred to as the "key expansion," is a crucial component of the Rijndael encryption algorithm (which is also known as AES when used with specific key and block sizes). The key schedule is responsible for generating the round keys used in the encryption and decryption processes. The key schedule operates differently based on the chosen key size (128, 192, or 256 bits).

Which AES algorithm is also known as Rijndael there are?

The AES algorithm that is also known as Rijndael is the one with a 128-bit block size and supports key sizes of 128, 192, and 256 bits. This specific configuration is often referred to as "Rijndael with a 128-bit block size" and is equivalent to the AES-128 encryption standard. In other words, AES-128 and Rijndael (with a 128-bit block size) are the same encryption algorithm.
