![]() ![]() Within your e-mail inbox, you are asked to re-enter your e-mail address and password on every single action you take (e.g., opening an unread e-mail or switching to a different inbox tab) to continuously verify your identity. Token-Based Authentication # Session-Based Authentication # Since Go is a popular choice for building server-side applications, Go's ecosystem offers many third-party packages for implementing these solutions into your applications.īelow, I'm going to show you how to integrate JWT authentication within a Go and chi application with the chi jwtauth middleware. In most cases, applications implement either session-based or token-based authentication to reliably verify a user's identity and persist authentication for subsequent page visits. Keep in mind that poorly designed authentication can easily be bypassed and introduce more vulnerabilities into your application. Asking for a stronger password decreases the likelihood of a malicious user correctly guessing it, but simultaneously, this password is increasingly more difficult for the user to remember. For example, a sign up form may prompt the user to enter a password that contains not only alphanumeric characters, but also must meet other requirements such as a minimum password length and containing punctuation marks. For developers, the difficulty in implementing authentication comes from striking a balance between the user experience and the strength of the authentication. ![]() You're busy, and you only want to spend a few minutes in your e-mail inbox before closing it out and resuming your day. Each time you log into your e-mail account and read your most recent unread messages, you, and like many other end users, don't think about how the service implements authentication to protect/secure your data and hide your activity history. In some cases, the service sends either a confirmation e-mail or an SMS text message to ensure that you own the supplied e-mail address or phone number.īecause it is highly likely that only you know the credentials to your account, authentication prevents unwanted actors from accessing your account and its data. When you first create an account, you provide this information in a sign-up form. Often, you must fill out a login form with credentials, such as an e-mail address and password, that uniquely identify your account. The signed JWT generated by Apigee Edge are valid and correctAccessing an e-mail account anywhere in the world on any device requires authenticating yourself to prove the data associated with the account (e.g., e-mail address and inbox messages) actually belongs to you.Base64-decoding the signature will never result in a printable string.If, when you try to decode the original signature string, you get a message saying "that's not a base64-encoded string", THEN you could conclude that the signature is not base64-encoded. But that doesn't mean the original wasn't encoded. When you base64-decode the signature value, you actually got a decoded value! It wasn't printable. Regarding your conclusion "the signature is not base64 encoded" that is not valid. And for that reason, the message you see is expected. That byte array is not printable, it does not represent ASCII or UTF-8 etc. Encoding it as base64, allows it to be printable. ![]() The message that says " No printable characters found," is expected. I understand the observations you are making. ![]()
