Use a dedicated, cryptographically secure —specifically one built on RNGCryptoServiceProvider or RandomNumberGenerator . Whether you are generating an AES-256 key for a database column or an HMAC secret for a JWT, the entropy source is the only thing that stands between your data and a breach.
In the world of cryptography, . We are creatures of pattern. If you ask a human to create a "random" 32-character string, they will likely avoid repeating characters, never use the same letter twice in a row, and probably start with a letter in the middle of the alphabet.

Need a quick key? Look for a tool at /all-keys-generator-random-security-encryption-key-generator.aspx —just make sure it uses System.Security.Cryptography under the hood. You need a key. So
We’ve all been there. You’re setting up a new SSL certificate, configuring a database connection string, or initializing an API authentication handler. You need a key. So, you type a few random characters on your keyboard: password123 . Done. configuring a database connection string
