Using the encryption feature of. Private API allows you to create and cancel new orders, and to check your balance. Thus, repeated calls are guaranteed never to reduce randomness. The GCM server and client APIs are deprecated and will be removed as soon as May 29, 2019. If you convert a byte array to a String, Java will try to decode the bytes into valid characters by using a charset (which in this case is defined by the platform just like kreiger said). These examples are extracted from open source projects. encodeHexString’ encodes to hex, not to base64, the former being the usual way of encoding hashes and MACs. AES (acronym of Advanced Encryption Standard) is a symmetric encryption algorithm. Java Security with MessageDigest.
