How to generate a secure value for JWT_SECRET

How to Create a High-Strength JWT_SECRET A secure secret must be long, random, and unpredictable . Simple phrases, dictionary words, or short strings are easily brute-forced or cracked using common tables. A good secret should be at least 32 bytes long (which results in a longer Base64 string) and generated using a cryptographically secure pseudo-random number generator (CSPRNG). Generating a Strong Secret Use your operating system's built-in cryptographic tools to generate the string. On Linux/macOS (Bash): The openssl rand command is a reliable way to generate a strong random string. The -base64 32 flag generates 32 cryptographically random bytes and encodes them in Base64 for safe use in environment files. Bash openssl rand -base64 32 On Windows (PowerShell): PowerShell offers a secure way to generate byte arrays using the .NET Framework's RNGCryptoServiceProvider . This ensures the randomness is suitable for cryptographic purposes. PowerShell $bytes=New-Object Byte[] ...
