# QRalo > QRalo generates cryptographically signed QR codes (Ed25519). When scanned via qralo.com/verify, the signature proves which organization issued the code, whether it was tampered with, and whether it is still active, expired, or revoked. ## What QRalo is - A signed QR code platform (authenticity + integrity of QRalo-issued codes) - Public verification at https://qralo.com/verify and scanner at https://qralo.com/scan - Optional checks against known-malicious URL lists at generation/scan time - Analytics, expiration, and instant revocation for issuers ## What QRalo is not - Not a universal anti-phishing product for every QR code in the world - Does not protect customers who scan non-QRalo / unsigned stickers unless they use a verifier and see that the code is not authentic - URL safety lists only catch already-known malicious URLs ## Key pages - https://qralo.com/ - https://qralo.com/secure-qr-codes - https://qralo.com/how-to-verify-qr-code - https://qralo.com/qr-code-restaurant - https://qralo.com/qr-code-parking - https://qralo.com/qr-code-phishing - https://qralo.com/scan ## Contact - contact@qralo.com - security@qralo.com
