Golang Snippet #12
This challenge covers the review of a snippet of code written in Golang
In this Code Review challenge, we analyze a snippet of Go (Golang) code designed to generate a secret string for signing JWT tokens. The code initializes a random secret using the current time to seed the random number generator. The process involves creating an array of random bytes and converting it to a string.
However, this code has significant vulnerabilities. The key issue is the use of math/rand instead of crypto/rand, as the former does not provide cryptographically secure random data. Additionally, seeding the random number generator with the current time makes the secret predictable and susceptible to brute-force attacks. An attacker could exploit this to forge JWT tokens, compromising the security of the application.
