If you use the referal link below, you get $10 free (1 or 2 months) https://m.do.co/c/5424d440c63a

2. Create a droplet and log in via ssh

I will be using the root user, but would suggest creating a new user

First of all, please note that token expiration and revoking are two different things.

Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:

How to check file integrity with shasum

For verifying the integrity (but not authenticity of data, i.e., who authored it or the origin of the file) of a file, it is necessary to run a checksum function on the file which will output a value and compare it to a previously stored checksum value; if both values match, we can be relatively confident that the file hasn't been tampered with or altered.

You might be asked to verify a file's sha1sum or sha2sum–-all this means is calculating and verifying the cryptographic sha1 or sha2 hash value or digest included in the file.

Various commands and methods for verifying shasum 1 or 2:

In terminal run:

Configure Mail Settings

Before you can send emails with ColdFusion, a mail server you want to use needs to be set. Configuring the mail server can be done in the ColdFusion Administrator.

If you do not have a mail server of your own, your localhost can act as a mail server. ColdFusion will act normally, but since there is no mail server set up on your localhost, emails will not arrive at their destination. Another option is to use the mail server of Gmail (a Gmail account is required for this). The settings for this mail server can be found at the end of this section.
