Helpful answers

We know there's a lot to learn and read about all that Hush can do. Here are some of the most frequently asked questions.

Hush secrets expire after 10 minutes so you can set-it-and-forget-it with secret key sharing.

All secrets are encrypted with AES 256. AES-256, which has a key length of 256 bits, supports the largest bit size and is practically unbreakable by brute force based on current computing power, making it the strongest encryption standard.

On the free plan you can send up to 5 secrets a month. On the paid plan you can send an unlimited amount of secrets.

By integrating with Key Management Service (KMS) in your own AWS account, Hush gives you tighter control over access to data. Use KMS in your own AWS account to create a Customer Master Key (CMK) that always stays under your control. Then, using key policies, you grant Hush access to use your CMK to generate and decrypt data keys. Please reach out to and we will enable this for the enterprise account.

You can share a secret in a channel and it can be accessed by the members of that channel - but your secret will expire after 10 minutes.

Nope. We display it once and then delete it. After that it's gone forever.
