Cryptography and identity

Protect data and identities.

📖 Key ideas

  1. Encryption protects confidentiality (AES, RSA).
  2. Hashing protects integrity; salted slow hashes protect passwords.
  3. TLS secures web traffic.
  4. Identity and access management: SSO, MFA, RBAC.
  5. Keys and secrets live in vaults, not code.
💡 Real-life example: Encryption is a locked box; identity management decides who gets which keys.
