Password hashing, personal data protection (GDPR)

Password hashing and personal data protection (GDPR)

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 reliable password hashing, encryption of user data, and strict compliance with legal requirements, including GDPR (General Data Protection Regulation).

How passwords are stored

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

Technology	Benefits
bcrypt	Reliable, slows down brute-force attacks
Argon2	Modern standard, side-channel protection
PBKDF2	Used 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

Principle	Casino Implementation
User Consent	Checkboxes and Registration Confirmation
Access right	Player can request all of their data
Right to delete ("right to be forgotten")	Request to delete account and all related data
Processing security	Protection of all forms of data input, storage and transfer
Minimize	Store only the information you need

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.
