The DES algorithm is a fixed-width encryption algorithm. Therefore, the input message is first padded to make sure that it will completely fit in “n” number of 64-bit blocks.

Data Encryption Standard (DES) – The DES encryption algorithm was developed in the 1970s. Although it has been widely deployed over the years, it has subsequently been superseded by other algorithms.

With experts suggesting that quantum computers will decrypt public key algorithms by 2030, quantum risk cryptography is becoming vital.

Behind the hype lies a grounded, strategic reality: transitioning to post-quantum cryptography is about preparation, not ...

The RSA operation for encryption and decryption is relatively simple as compared to other cryptographic algorithms, but the magic of RSA lies in the keys. Key generation in RSA is less simple than the ...

A basic tenet of modern cryptography is that the entire security of an encrypted message should rest with the encryption key, not with the encryption algorithm.

Explore how blockchain cryptography safeguards digital assets through encryption, hash functions, and advanced techniques ...

Quantum computing is a catalyst for rethinking how organizations govern, secure and manage cryptographic systems.

Quantum computing represents a significant shift in technology, with the potential to break widely-used public key cryptography and encryption algorithms like RSA and ECDSA by 2030. This looming ...

The winner, a group of cryptographic algorithms called Ascon, will be published as NIST’s lightweight cryptography standard later in 2023. The chosen algorithms are designed to protect information ...
