Introduction to SecureVault

Welcome to SecureVault, your secure file storage and encryption solution. This guide will walk you through all the features of the application and how to use them effectively.

SecureVault uses advanced encryption techniques including RRPBA (Rounds-based Permutation Block Algorithm) to ensure your files remain private and secure.

Note: SecureVault is designed with security in mind. All encryption and decryption happens on the server, protecting your encryption keys from exposure.

Troubleshooting Common Issues

File Upload Errors

Problem: "413 Request Entity Too Large" error when uploading files.

Solution: The file exceeds the maximum upload size limit. Try uploading a smaller file.

Long Encryption/Decryption Times

Problem: Encryption or decryption takes a very long time.

Solution: This is normal for larger files. Consider encrypting smaller chunks of data if possible.

Download Timeout Errors

Problem: "504 Gateway Timeout" error when downloading large encrypted files.

Solution: For very large files:

  • Decrypt the file first, then download it separately
  • Split large files into smaller segments before encryption

Lost Encryption Keys

Problem: You deleted an encryption key that was used for files.

Solution: Always decrypt files before deleting keys. Files encrypted with deleted keys are permanently inaccessible.
