I'd prefer to use ed25519, but there isn't a fast java version. Bouncy Castle support contracts are available though Crypto Workshop. According to your explanation I think that BC output it in short-Weierstrass format, while i need it in Montgomery curve format. This class convert the Montgomery X coordinate to a Weierstrass X coordinate via the point map: build a SEC compressed point encoding for the Weierstrass X coordinate, ...which can then be passed to decodePoint. By … This can be made to work by converting the input as follows: If you want to also send a public key in X25519 format, you'll need to do a similar conversion (Xm = Xw - D mod P) from the point encoding you get from the Weierstrass curve. Also, X25519 permits public keys on the twist of the curve, which will instead cause exceptions in SW implementations. Without that, there is no going forward. The choice here is guided by language in the Ed25519 paper. A provider for the Java Cryptography Extension (JCE) and the Java Cryptography Architecture (JCA). More than 50 million people use GitHub to discover, fork, and contribute to over 100 million projects. This document defines the Security Policy for the Legion of the Bouncy Castle Inc. FIPS Java API (BC-FJA) Module, hereafter denoted the Module. Bouncy Castle Java Distribution (Mirror). I need to create a shared secret for the DH (Diffie–Hellman Key Exchange), using my private key and a public key that I receive from Apache Server. ...

X25519 uses the Montgomery curve "Curve25519", and specifies the public key format as the (exactly) 32-byte X coordinate (little-endian). Returns a stream for the resource with the specified name. This includes at least, but not exclusively the following parts: ASN.1 Object identifiers Contribute to bcgit/bc-java development by creating an account on GitHub. So it's not clear to me that it can be made to work in the general case, without stepping outside of JCE and doing parts of the operations yourself. If you don't have Bouncy Castle, go to Bouncy Castle latest releases to download the provider file that corresponds to your JDK. A clean room implementation of the JCE 1.2.1. pairA = kpgen.generateKeyPair(); Consequently, we will download JAR: ‘bcprov-jdk15on-165.jar’ applicable for JDK 1.5 to JDK 1.11. This jar contains S/MIME APIs for JDK 1.5 to JDK 1.8. * The Curve25519 paper doesn't say which of the two possible y values the base. PowerAuth server uses dynamic initialization of Bouncy Castle provider, so it is not required to configure security provider statically in the Java Runtime configuration. Throughout the rest of this article, I’m going to focus on Ed25519. You signed in with another tab or window. The package is organised so that it contains a light-weight API suitable for use in any environment (including the J2ME) with the additional infrastructure to conform the algorithms to … * involves substitution of variables, so the base-point x coordinate is 9 + (486662 / 3). GitHub is where people build software. Prior to switching that project to curve25519, I'd already written code that uses an ed25519 library in Java, where the ed25519 library was borrowed from the NEM project. The Bouncy Castle Java CMS and S/MIME APIs for handling the CMS and S/MIME protocols. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. Skip to the last paragraph for the easy solution, or read on if you need to make things work via the provider code above. The first step when supporting a new algorithm for PKI usage, in Java, is to get all the ASN.1 and Java crypto stuff in place. It should be clear how to use it by referring to the X25519Test.testECDH method.

X9ECParameters ecP = CustomNamedCurves.getByName("Curve25519"); Bouncy Castle is a collection of APIs used in cryptography.It includes APIs for both the Java and the C# programming languages. The way that private keys are generated and/or used in X25519 have some subtle differences compared to JCE providers' behaviour for generic SW curves. The getKey() method returns the private key associated with a given alias.. We have more work to do on trying to present that in the provider and through the usual interfaces, but if you just want to do ECDH with X25519, you could use that class directly (copy it for now, or wait for the next release - or beta). This release adds Ed25519/Ed448 to the TLS API and BCJSSE provider as well as further support for SNI and OCSP stapling. The choice here is guided by language in the Ed25519 paper.
