Apa Itu MD5 Hash ?

Pertama tama ada yang tau MD5 itu apa.? Kalau nggak tau saya akan memberikan penjelasan terlebih dahulu tentang apa itu MD5, walaupu ambinya di Wikipedia Sih :D


Dalam kriptografi, MD5 (Message-Digest algortihm 5) ialah fungsi hash kriptografik yang digunakan secara luas dengan hash value 128-bit. Pada standart Internet (RFC 1321), MD5 telah dimanfaatkan secara bermacam-macam pada aplikasi keamanan, dan MD5 juga umum digunakan untuk melakukan pengujian integritas sebuah berkas.
MD5 di desain oleh Ronald Rivest pada tahun 1991 untuk menggantikan hash function sebelumnya, MD4. Pada tahun 1996, sebuah kecacatan ditemukan dalam desainnya, walau bukan kelemahan fatal, pengguna kriptografi mulai menganjurkan menggunakan algoritma lain, seperti SHA-1 (klaim terbaru menyatakan bahwa SHA-1 juga cacat). Pada tahun 2004, kecacatan-kecacatan yang lebih serius ditemukan menyebabkan penggunaan algoritma tersebut dalam tujuan untuk keamanan jadi makin dipertanyakan.

Hash MD5
Hash-hash MD5 sepanjang 128-bit (16-byte), yang dikenal juga sebagai ringkasan pesan, secara tipikal ditampilkan dalam bilangan heksadesimal 32-digit. Berikut ini merupakan contoh pesanASCII sepanjang 43-byte sebagai masukan dan hash MD5 terkait:

MD5("The quick brown fox jumps over the lazy dog") = 9e107d9d372bb6826bd81d3542a419d6

Bahkan perubahan yang kecil pada pesan akan (dengan probabilitas lebih) menghasilkan hash yang benar-benar berbeda, misalnya pada kata "dog", huruf d diganti menjadi c:

MD5("The quick brown fox jumps over the lazy cog") = 1055d3e698d289f2af8663725127bd4b

Hash dari panjang-nol ialah:
MD5("") = d41d8cd98f00b204e9800998ecf8427e
OK saya anggap kalian kawan kawan sudah tau MD5 itu apa :D
