1. Securely store and transmit cardholder data.

2. Verify the authenticity of transactions.

3. Detect and prevent fraudulent activity.

4. Comply with industry standards and regulations.

The use of SHA-256 in payment processing ensures that sensitive payment information is protected from unauthorized access, tampering, or breaches, maintaining the trust and confidence of customers and merchants.

Some payment processing regulations and standards that require the use of SHA-256 include:

1. PCI-DSS (Payment Card Industry Data Security Standard)

2. PA-DSS (Payment Application Data Security Standard)

3. GDPR (General Data Protection Regulation)
