Encryption for translators — NDAs and confidential source texts

Freelance translators sign NDAs for a living. Elba is the simplest way to meet the ‘encryption at rest’ clause most of those contracts contain — a sealed per-client vault on your own machine.

A vault per client

Source texts, translation memories, glossaries, and drafts all sealed together. Delivery goes through the client's usual channel; the working copy stays in the vault.

After delivery

Keep the sealed vault for the contractual retention period, then delete. AES-256-GCM without the password is effectively noise.
