PDF Password & Encryption Security
Standard PDFs support robust native encryption. The /Encrypt dictionary defines the algorithm (RC4, AES-128, AES-256) and manages two distinct passwords: the User password (required to open the file) and the Owner password (required to modify permissions like printing or copying).
These files ensure your processing pipelines fail gracefully—or correctly prompt the user for a password—when encountering natively encrypted documents. All files use the password "spytm".
AES-128
Encrypted using legacy AES-128 algorithms to ensure backward compatibility in decryption libraries.
AES-256
Encrypted using modern AES-256 algorithms to test advanced cryptography libraries.
User password
Protected with a standard User password ("spytm") to test basic decryption UI prompts.
Owner password
Protected with an Owner password restricting copying and printing, testing permission-enforcement logic in PDF viewers.
Frequently Asked Questions
Use Cases
- Testing malware scanners to ensure they gracefully time-out or reject encrypted payloads rather than hanging.
- Validating UI flows that intercept `EncryptedDocumentException` and prompt the end-user for a password.
- Testing backend decryption queues using standard AES-256 algorithms.
