This rule pertains to the size of RSA keys used in your Ruby applications. RSA is a widely used encryption algorithm and the size of the key is crucial for the security of the data it protects. If the key is too small, it can be easily cracked using modern computational power, exposing sensitive data to potential threats.
The importance of this rule cannot be overstated. In modern security standards, a minimum of 2048 bits is recommended for RSA keys. Using a key size less than this, such as 512 bits, can lead to vulnerabilities that can be exploited by attackers.
To adhere to good coding practices and avoid violating this rule, always ensure that the size of your RSA keys is at least 2048 bits. This can be done by initializing your RSA key with the value 2048 as shown in the compliant code example: OpenSSL::PKey::RSA.new 2048. Avoid initializing your RSA keys with smaller values such as 512 to prevent potential security risks.
