I have a batch of Word, Excel, PDF and similar office documents stored locally on my PC and an external SSD. I need each of them placed behind strong AES-256 encryption so I can move them off-site without worrying about exposure.
Your task is to take the raw files I supply, encrypt them offline, and hand back either (a) the individual encrypted files or (b) a single encrypted container—whichever you feel is safest and most efficient. I will provide the master passphrase; you may use VeraCrypt, 7-Zip, GnuPG, OpenSSL or another modern, peer-reviewed tool as long as the resulting files can be decrypted on both Windows and macOS.
Because data integrity is critical, include a quick checksum or hash comparison (SHA-256 is fine) showing that every original file matches its encrypted counterpart once decrypted. We will transfer the originals and the finished set through a secure, agreed-upon channel—Proton Drive, VPN-protected SFTP, or a GPG-encrypted archive. No cloud sharing without encryption at rest.
Deliverables
• Encrypted copies (or container) of all supplied documents
• Clear, step-by-step decryption guide with any necessary keys kept separate from the files
• Verification report listing original and post-encryption hashes
If you have a proven track record in file-level encryption and can complete the job quickly, let me know which toolset you prefer and how you intend to validate the results.
