ENCRYPTION & SECURITY

Tayf utilizes state-of-the-art protocols to ensure that pilgrim data remains private, secure, and resilient against modern cyber threats.

End-to-End Encryption (E2EE)

Every message, image, and call is encrypted on the sender's device and decrypted only at the receiver's end. Not even our servers can access the content.

Signal Protocol Implementation

Advanced Algorithms

Utilizing AES-256 for content encryption, Curve25519 for key exchange, and HMAC-SHA256 for integrity verification.

AES-256 / RSA-2048 / HMAC

Dynamic Key Management

Each conversation has its own unique encryption key generated locally with Perfect Forward Secrecy (PFS) for automatic renewals.

Local Key Generation

Data-at-Rest Security

Local databases are secured via Secure Enclave/Keystore. All cloud-stored files are encrypted before transmission.

Secure Enclave Hardware

Threat Monitoring

Real-time threat logging to prevent unauthorized access, DDoS protection, and brute-force mitigation.

Continuous Audit Logging

Privacy Controls

GDPR-compliant privacy tools including visibility toggles, chat hiding, and 'Right to be Forgotten' data deletion.
