Openssl generate random aes 256 key

There are multiple ways of generating an encryption key. Most implementations rely on a random object. All examples mentioned here use a secure cryptographic randomizer.

OpenSSL is well known for its ability to generate certificates but it can also be used to generate random data. Generates 32 random bytes (256bits) in a base64 encoded output: openssl rand -base64 32 Plaintext. Generates 32 random characters (256bits): openssl rand 32. I'm not aware of one. If you're going to integrate a crypto library into your project, then you can use OpenSSL for AES-GCM. Note that the cipher you're choosing here is only being used to encrypt the private key (and I see no particularly compelling reason for a private key to be encrypted using AES-GCM).
