      The rule makes sure you are using randomly generated IVs and keys
      for Crypto calls. Hard-coding these values greatly compromises the
      security of encrypted data.
    pattern-either:
      - pattern: Blob $IV = Blob.valueOf('$STRING');...Crypto.encrypt($ONE, $TWO, $IV, $FOUR);
      - pattern: Blob $IV = Blob.valueOf('$STRING');...Crypto.decrypt($ONE, $TWO, $IV, $FOUR);
      - pattern: Blob $KEY = Blob.valueOf('$STRING');...Crypto.encrypt($ONE, $KEY, $THREE, $FOUR);
      - pattern: Blob $KEY = Blob.valueOf('$STRING');...Crypto.decrypt($ONE, $KEY, $THREE, $FOUR);
