Elliptic-Curve Cryptography (Ecc) and Argon2 Algorithm in PHP Using Openssl and Sodium Libraries

Abstract

This paper presents the elliptic-curve cryptography (ECC) and Argon2 algorithm in PHP using OpenSSL and Sodium cryptographic libraries. The vital part of this thesis presents an analysis of the efficiency of elliptic-curve cryptography (ECC) and the Argon2 hashing algorithm in the Sodium library, depending on the variation of initiation parameters.

“…Being slower compared to Argon2d helps provide better security from tradeoff attacks. It is slower because it uses the memory at a speed of two processor cycles per byte [54]. Argon2d on the other hand uses data-dependent memory access and is better suited for applications such as backend servers and cryptocurrencies, where sidechannel attacks are not a threat [55].…”
