Providers are testing a quantum-safe version of HTTPS that shrinks certificates to a tenth their previous size, decreasing ...

Birthday attacks exploit the collision probability of hash functions. Collision resistance requires sufficiently large hash outputs. Modern blockchains use 256-bit hashes to mitigate collision risks.

Cryptography secures communication in banking, messaging, and blockchain. Good algorithms (AES, RSA, ECC, SHA-2/3, ChaCha20) are secure, efficient, and widely trusted. Bad algorithms (DES, MD5, SHA-1, ...

Blake3 is not listed as secure hashing algorithm in NIST SP 800-140Cr2 and therefore not FIPS 140 compliant. It's not clear if the choice and properties of the hashing algorithm is security relevant.

a Python command-line tool that identifies and groups similar images using average hashing. It supports single-level and recursive directory scanning, adjustable similarity threshold, and presents ...

ABSTRACT: When developing programs or websites, it is very convenient to use relational databases, which contain powerful and convenient tools that allow to work with data very flexibly and get the ...

Abstract: Secure hash functions are widely used in cryptographic algorithms to secure against diverse attacks. A one-way secure hash function is used in the various research fields to secure, for ...

Abstract: To verify the integrity and confidentiality of data communicated through the web is a very big issue worldwide because every person wants very fast computing and secure electronic data ...
