Key Generation

RSA Keys

# Generate RSA private key (2048-bit)
openssl genrsa -out private.key 2048

# Generate RSA private key (4096-bit, more secure)
openssl genrsa -out private.key 4096

# Generate encrypted RSA private key
openssl genrsa -aes256 -out private.key 4096

# Extract public key from private key
openssl rsa -in private.key -pubout -out public.key
