SHA2 ve SHA256 aynı değildir, ancak SHA2 ailesinin bir parçasıdırlar. SHA2, ABD hükümeti tarafından geliştirilen ve çeşitli hash fonksiyonları içeren bir ailedir. SHA256 ise özellikle 256-bit hash değeri üreten bir SHA2 varyantıdır.
SHA-4 algoritması kaldırılmadı, çünkü SHA-1 algoritması güvenlik açıkları nedeniyle kullanımdan kaldırıldı. SHA-1'in zayıf yönleri, algoritmanın phishing ve man-in-middle saldırılarına karşı yeterince güvenli olmamasıydı.
