Password hashing and personal data protection (GDPR)
Click to expand / collapse

In online casinos, the player trusts the platform not only money, but also personal information: name, email, phone, documents. Therefore, the operator's task is to ensure the complete security of this data. This is achieved through strong password hashing, encryption of user data, and strict compliance with legislation, including GDPR (General Data Protection Regulation).


How passwords are stored

Passwords are never stored "clean." Instead, a hash function is used - a one-way algorithm that turns the password into an encrypted string that cannot be recovered back.

TechnologyAdvantages
bcryptReliable, slows down brute-force attacks
Argon2Modern standard, side-channel protection
PBKDF2Used in banking systems
Additionally applied:
  • Salt - A unique value for each password
  • Retray mechanisms - limiting entry attempts
  • 2FA - Second Authorization Factor

Personal data protection

All user information (personal data, documents, transaction history) is processed in accordance with international privacy standards.

Key measures:
  • Database-level encryption (AES-256, RSA)
  • SSL/TLS connections at all stages
  • Account data isolation
  • Storage of access logs and changes
  • Ability to upload and delete data on demand (GDPR)

What GDPR (and similar laws) require

PrincipleCasino Implementation
User consentCheckboxes and confirmation at registration
Right of accessThe player can request all his data
Right to be removed ("right to be forgotten")Request to delete account and all related data
Processing securityProtect all forms of data capture, storage, and transmission
MinimizationOnly necessary information is stored

Additional security measures

Monitoring leaks and hacking attempts

Device Fingerprinting for Access Control

New Device/IP Logon Notifications

Split access by role (admin, support, player)

Logging of all personal data transactions


Password hashing and personal data protection is a mandatory standard for responsible online casinos. GDPR compliance, encryption, secure authorization and transparent data processing policies not only ensure legal purity, but also build trust on the part of players. And trust is the foundation of long-term success.
