Connect to CalDav (Beta)

[charleslcso]

I have an active working radicale server.

Now I try to connect to it via Connect to CalDav (Beta), but it says Invalid key length.

Please advise how to set it up.

The "Invalid key length" error likely relates to the encryption key used for securing CalDav connections. In the Cal.com codebase, the symmetric encryption function uses the AES256 algorithm, which requires a key length of 32 bytes. You need to ensure that the CALENDSO_ENCRYPTION_KEY environment variable is set to a 32-byte value.

You can generate a suitable key using the following command:

openssl rand -base64 32

Make sure to set this generated key in your environment configuration. This should resolve the "Invalid key length" error when connecting to your Radicale server ^[1][2].

Yes, after updating the CALENDSO_ENCRYPTION_KEY environment variable, you should restart your server to ensure the changes take effect. This will apply the new configuration and should resolve the "Invalid key length" error.

It doesn’t not solve the error. I generated the key using your command using openssl.

Ensure that the CALENDSO_ENCRYPTION_KEY is correctly set in your environment configuration file and that the server is using this updated configuration. Here are a few steps to verify:

1. Check the Key Length: Make sure the key you generated is exactly 32 bytes. You can verify this by decoding the base64 string and checking its length.

2. Environment Configuration: Double-check that the .env file or the environment variable configuration used by your server includes the correct CALENDSO_ENCRYPTION_KEY.

3. Server Restart: After updating the environment variable, ensure the server is fully restarted, not just reloaded, to apply the new configuration.

4. Logs and Errors: Check the server logs for any additional error messages that might provide more context on why the connection is failing.

If the issue persists, there might be other configurations or dependencies affecting the setup.

The "Invalid key length" error you're encountering indicates that the encryption key used in the symmetricEncrypt function is not of the required length for AES256, which must be exactly 32 bytes. Here are some steps to troubleshoot and resolve this issue:

1. Verify Key Length: Ensure that the key you generated is exactly 32 bytes. You can verify this by decoding the base64 string and checking its length. The command openssl rand -base64 32 should generate a key of the correct length, but it's important to confirm.

2. Environment Configuration: Double-check that the CALENDSO_ENCRYPTION_KEY is correctly set in your environment configuration file (e.g., .env). Ensure there are no extra spaces or characters in the key.

3. Server Restart: After updating the environment variable, perform a full server restart to ensure the new configuration is applied. A simple reload might not suffice.

4. Check for Hardcoded Values: Ensure there are no hardcoded values in the code that might be overriding the environment variable.

5. Review Logs: Continue to review the server logs for any additional error messages that might provide more context on the issue.

If the problem persists after these checks, there might be other configurations or dependencies affecting the setup.

The error message "Could not add this caldav account" could be due to several reasons. Here are some steps to help troubleshoot and resolve the issue:

1. Check Credentials: Ensure that the CalDav account credentials (username, password, and URL) are correct. Incorrect credentials can prevent the account from being added.

2. Verify Encryption Key: Double-check that the CALENDSO_ENCRYPTION_KEY is correctly set and is exactly 32 bytes long. This key is crucial for encrypting the credentials.

3. WebDAV Authentication: If the error message indicates "Invalid credentials" and the URL contains "dav.php", verify that the WebDAV authentication type is set to "Basic". This is a common requirement for some CalDav servers ^[1].

4. Server Logs: Review the server logs for any additional error messages that might provide more context on why the account could not be added. This can help identify specific issues related to the CalDav integration.

5. Network Configuration: Ensure that there are no network issues or firewall settings blocking the connection to the CalDav server.

6. Database Configuration: Check that the database is properly configured and accessible, as the credentials are stored using Prisma.

If these steps do not resolve the issue, there might be other configurations or dependencies affecting the setup.
