For developers
Share API keys without Slack seeing plaintext
Cryptbin encrypts snippets, files, and env bundles in your browser before upload. Send a link instead of dropping secrets into chat history, email, or a ticket that outlives the handoff.
What developers use it for
Cryptbin is the encrypted courier for the share you cannot put in a public channel — not a secrets manager or password vault replacement.
API keys and tokens
Hand off staging credentials to a contractor or vendor without pasting secrets into Slack or email threads that live forever.
.env bundles and configs
Share a full environment block as structured secrets — labels stay readable after decrypt, values stay encrypted at rest.
Snippets with syntax hints
Paste JSON, YAML, or shell scripts with optional syntax highlighting for the recipient — ciphertext only on the server.
Onboarding and support handoffs
Send temporary access details to a teammate or customer with expiry or burn-after-read so the link cannot be reused.
One-time production secrets
Use burn-after-read when a secret should disappear after the first successful open — useful for break-glass or incident response.
Typical handoff
# Paste this into Cryptbin instead of Slack STRIPE_SECRET_KEY=sk_live_... DATABASE_URL=postgres://... REDIS_URL=redis://... → Encrypt in browser → copy link → send once → burn after read
When Cryptbin fits better than chat or email
You still need a secrets manager for long-term storage. Cryptbin is for the one-off share that should not linger in plaintext.
Cryptbin gives you
- Client-side encryption before anything is uploaded
- Decryption key in the URL fragment (legacy mode)
- Expiry and burn-after-read for one-time handoffs
- Structured secrets for .env-style bundles
What to use elsewhere
- 1Password / Vault for durable team credential storage
- Slack or email for non-sensitive coordination only
- Your CI/CD secret store for production automation
Start with one encrypted handoff
Try a staging API key, onboarding .env, or support credential. Keep long-term secrets in your vault — keep the courier encrypted.
