We require client authentication to send a RESTful request to some of our web services. I've installed a client cert (.pem) and key on the my local mac os via the key tool. These are not self signed. openssl pkcs12 -export -name myservercert -in not_self_signed.crt -inkey server.key -out keystore.p12 ...and converted to JKS format keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert I'm trying to build a Java client to do the authentication. Here is what I've come up with so far: import java.io.FileInputStream; import java

I'm implementing a validator for validating incoming requests from Amazon Alexa . I'm on step 5 and 6 which state: 5) base64-decode the Signature header value on the request to obtain the encrypted signature. 6) Use the public key extracted from the signing certificate to decrypt the encrypted signature to produce the asserted hash value. I've managed to extract the public key from the PEM-encoded X.509 certificate by doing: $publicKey = openssl_pkey_get_public($pem); $keyData = openssl_pkey_get_details($publicKey); Which returns my public key. I've then attempted to decrypt the signature like

I have lost private key of my AWS instance.I searched the option in console panel. I'm afraid you might be out of luck: When you launch an instance, you should specify the name of the key pair you plan to use to connect to the instance. If you don't specify the name of an existing key pair when you launch an instance, you won't be able to connect to the instance. When you connect to the instance, you must specify the private key that corresponds to the key pair you specified when you launched the instance. Amazon EC2 doesn't keep a copy of your private key; therefore, if you lose a private key

We are adding server certificates verification in SSL handshake for one of our clients. Being very new to Cryptography and C world, thought I would first clear my concepts about these things and then start with implementation. So, I googled a lot looking mostly for Certificates concepts, but couldn't clear up my concepts any better to my satisfaction. Actually it added more confusion. :) Here are some things which I don't understand almost at all: 1. What is base64 format? Is it same as DER? 2. PEM file always contains base64 content? 3. What is the format used by Windows Certificate Store? Is

Hi I am a little new to all this openSSL and PEM stuf, so I thought I would ask you people here. I have a certificate in text(X509) format like this for example Certificate: Data: Version: 3 (0x2) Serial Number: 1f:19:f6:de:35:dd:63:a1:42:91:8a:d5:2c:c0:ab:12 Signature Algorithm: PKCS #1 SHA-1 With RSA Encryption Issuer: "CN=Thawte SGC CA,O=Thawte Consulting (Pty) Ltd.,C=ZA" Validity: Not Before: Fri Dec 18 00:00:00 2009 Not After : Sun Dec 18 23:59:59 2011 Subject: "CN=mail.google.com,O=Google Inc,L=Mountain View,ST=Californ ia,C=US" ............................................ ..............

I'm trying to establish successful communication over an HTTPS connection using authentication. I'm using Python 2.7 w/ Django 1.4 on Ubuntu 12.04. The API documentation I'm following has specific requirements for authentication. Including the Authentication header you'll find below and sending certificate information. This is the code: import httplib import base64 HOST = 'some.host.com' API_URL = '/some/api/path' username = '1234' password = '5678' auth_value = base64.b64encode('WS{0}._.1:{1}'.format(username, password)) path = os.path.join(os.path.dirname(__file__), 'keys/') pem_file = '{0

How convert RSA public key, from XML to PEM (PHP)? we know .pem - (Privacy Enhanced Mail) Base64 encoded DER certificate, enclosed between "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" X.509 The SignatureValue element contains the Base64 encoded signature result - the signature generated with the parameters specified in the SignatureMethod element - of the SignedInfo element after applying the algorithm specified by the CanonicalizationMethod. XML_Signature so we end up with $xml = simplexml_load_file($xmlFile); // or simplexml_load_string $pem = "-----BEGIN CERTIFICATE-----\n"

I have a RSA Key and a X.509 Certificate which I use for SSL connections. The key and certificate are stored in files in PEM format (generated by OpenSSL) and used in an Apache HTTP server environment. Is there an easy way to validate if the key matches the certificate using only Java code (without executing the openssl binary and parsing the output), for example by using Java security and/or Bouncycastle library methods? The following code compares the SHA-1 over the modulus within the public and private key. The modulus should be unique for each pair (unless you key pair generation mechanism
