### Question:
Certificate { private static boolean verify(String body, String signature, PublicKey publicKey) { try { Signature sign = Signature.getInstance("SHA1WithRSA"); sign.initVerify(publicKey); sign.update(body.getBytes("UTF-8")); return sign.verify(Base64.decodeBase64(signature.getBytes("UTF-8"))); } catch (Exception e) { return false; } } Certificate(final String signature, final String signaturecerturl, final String message);  Certificate(HttpServletRequest request); static boolean verify(ConcurrentHashMap<String, PublicKey> cache, Certificate certificate); static PublicKey getPublicKeyFromUrl(String signaturecerturl); String getSignature(); String getSignaturecerturl(); String getMessage();  }### Answer:
@Test public void testVerify() { fail("Not yet implemented"); }
