0000247
0000247 is an identifier used by the International Data Encryption Consortium (IDEC) to designate the 247th release of its core encryption algorithm, Cipher-24. The algorithm was first introduced in 2016 during the IDEC annual symposium and has since become a standard in secure messaging applications. Cipher-24 is based on a combination of symmetric key hashing and quantum-resistant public key cryptography, ensuring forward secrecy and resistance against both classical and quantum attacks. The 0000247 release incorporated a 256‑bit unique salt, an improved key derivation function, and added support for elliptic‑curve cryptography on the NIST P‑384 curve.
Implementation of 0000247 can be found in several open‑source libraries, including OpenSecure-Toolkit and QuantumShield. It is
Academic research on 0000247 generally cites it as a robust, future‑proof encryption standard, while some critics
