Online RC6 Encryption Tool
Tool Introduction:
The Online RC6 Encryption Tool lets you encrypt data using RC6. Supports ECB, CBC, CFB, OFB, and CTR modes. Flexible key length (0–2040 bits). Padding options include PKCS#5, PKCS#7, Zeros, ISO10126, ANSI X.923, ISO/IEC 7816-4, and NoPadding. Input supports UTF-8, Base64, and Hex; output supports Base64 and Hex, with case toggle for Hex.
About RC6 Encryption Algorithm:
RC6 (Rivest Cipher 6) is a symmetric key encryption algorithm and the sixth generation of the RC series encryption algorithms. RC6 was designed by Ron Rivest, Matt Robshaw, Ray Sidney, and Yiqun Lisa Yin as a further development of the RC5 algorithm to meet the requirements of the Advanced Encryption Standard (AES) competition. RC6 was one of the five final selected algorithms in the AES algorithm public selection, although the Rijndael algorithm was ultimately chosen as the AES standard. RC6 inherits the advantages of RC5, uses data-dependent rotation concepts, and enhances resistance to attacks. RC6 has a block size of 128 bits, uses 4 registers, and employs 32-bit integer modular multiplication operations to enhance diffusion characteristics. The operations used in the RC6 algorithm can be efficiently implemented on most processors, improving encryption speed.
