Babagan HMAC

HMAC (Hash-based Message Authentication Code) is a mechanism for calculating a message authentication code (MAC) involving a cryptographic hash function in combination with a secret cryptographic key. It can be used to verify the integrity and authenticity of a message.

HMACs tahan kanggo serangan extension dawa lan menehi cara kanggo mesthekake yen pesen wis ora tampered karo lan sing pangirim sing padha ngaku. Keamanan HMAC gumantung marang kekuwatan kriptografi saka fungsi hash sing ndasari lan rahasia kunci kasebut.

Note:Tombol sing digunakake ing HMAC kudu didhelikake. Tombol sing beda kudu digunakake kanggo tujuan sing beda, lan kunci kudu digawe nggunakake generator nomer acak kanthi aman cryptographically.

Kasus Penggunaan Umum

  • API panjalukan bukti asli
  • Transmisi pesen sing aman
  • Verifikasi integritas data
  • Token otentikasi sesi
  • Verifikasi file utawa data
