Documentation

Secure coding practices prescribe to use RSA to generate key pairs.

Asymmetric encryption requires a pair of keys, a private and a public key. This enables authenticity on top of confidentiality in the encryption algorithm. Authenticity is a requirement for some secure communication channels. That means that asymmetric cryptography is typically used in a scheme for signatures or a key agreement and not for bulk encryption of data. It is recommended to use RSA for key pair generation.

Correct code example
keyPairGenerator = KeyPairGenerator.getInstance("RSA");
