EnvShare

EnvShare is a simple tool to share environment variables securely. It uses AES-GCM to encrypt your data before sending it to the server. The encryption key never leaves your browser.

• End-to-End Encryption: AES-GCM encryption is used to encrypt your data before sending it to the server
• Limit number of reads: Limit the number of times a link can be read
• Auto Expire: Automatically expire links and delete data after a certain time

Built with

• Next.js

API

PLEASE NEVER EVER UPLOAD UNENCRYPTED SECRETS.

This endpoint is only meant to store already encrypted secrets. The encrypted secrets are stored in plain text.

1
$ curl -XPOST -s https://envshare.dev/api/v1/secret -d "already-encrypted-secret"

You can add optional headers to configure the ttl and number of reads.

1
$ curl -XPOST -s https://envshare.dev/api/v1/secret -d "already-encrypted-secret" -H "envshare-ttl: 3600" -H "envshare-reads: 10"

• Omitting the envshare-ttl header will set a default of 30 days. Disable the ttl by setting it to 0. (envshare-ttl: 0)
• Omitting the envshare-reads header will simply disable it and allow reading for an unlimited number of times.

This endpoint returns a JSON response with the secret id:

1
{
2
  "data": {
3
    "id": "HdPbXgpvUvNk43oxSdK97u",
4
    "ttl": 86400,
5
    "reads": 2,
6
    "expiresAt": "2023-01-19T20:47:28.383Z",
7
    "url": "http://envshare.dev/api/v1/secret/HdPbXgpvUvNk43oxSdK97u"
8
  }
9
}

You need an id to retrieve a secret. The id is returned when you store a secret.
