  script_tag(name:"insight", value:"When calling EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() or
  EVP_CipherInit_ex2() the provided OSSL_PARAM array is processed after the key and IV have been
  established. Any alterations to the key length, via the 'keylen' parameter or the IV length, via
  the 'ivlen' parameter, within the OSSL_PARAM array will not take effect as intended, potentially
  causing truncation or overreading of these values. The following ciphers and cipher modes are
  impacted: RC2, RC4, RC5, CCM, GCM and OCB.");
