However, POC requests something specific as well as general. POC doesn't place any restrictions on topic. POC really hates such a topic with a tempting title but nothing in it. If (omByteArray(ciphertext) = base64js.POC is one of the very small number of best technical 'hacking' conferences in the world. Var ciphertext2 = byte_array.subarray(10, byte_array.length) Var buf = new ArrayBuffer(ciphertext.length + 10) Var ciphertext = base64js.toByteArray(ciphertext_base64_str) Since Safari supports RSA-OAEP 'RSA-OAEP mod:2048 pubExp:3 format:jwk' you should be able to get AES-GCM working in Safari with the library as is.Ĭan you explain what your target scenario is that is not covered by the library? arraybuffer bug This is generally working great with a combination of Square's JS and Golang JOSE libraries, with the glaring exception of WebKit, which is blocking iOS yes, our goal was to minimize use of the JS implementations and use the native implementations when present.

My application needs to be able to download an RSA public key in JWK format (had too much trouble with dueling PEM implementations), generate a AES-GCM key in as safe fashion as possible, encode an arbitrary payload as a JWE with it, wrap that key with RSA-OAEP, and have the result be downloadable and decryptable by a different application running potentially on a different platform that possesses the corresponding RSA private key.
Perhaps I don't know enough about JavaScript to know whether one could actually fake out the browser's implementation with a key implemented outside. A brief glance at the RSA keywrap function suggests that it won't work with AES-GCM keys also generated by webcrypto-liner, as it is expecting the key to be wrapped to be processable by the browser's crypto. Thanks it might be a helpful starting point. It works on OSX Safari, but it doesn't work on my iPhone safari (iOS version 10.3.2). You can see the webcrypto-liner in use in the pv-webcrypto-tests page. We recommend against its use unless needed for interoperability.Ģ K-256 (secp256k1) curve is not defined by the WebCrypto specifications. Use of mechanism in a safe way is hard, it was added for the purpose of enabling interoperability with an existing system. P-256, P-384, P-521, and K-256 2 (secp256k1)ġ Mechanism is not defined by the WebCrypto specifications. RSA-OAEP, DES-CBC 1, DES-EDE3-CBC 1, AES-ECB 1, AES-CBC, AES-ECB and AES-GCMĪES-GCM, AES-CBC, AES-ECB 1, DES-CBC 1, DES-EDE3-CBC 1 Webcrypto-liner supports the following algorithms and key lengths: Capability If you do not load any of the dependencies that provide cryptographic implementations webcrypto-liner will work as an interoperability layer, very similar to webcrypto-shim. To keep webcrypto-liner as small as possible (right now it is ~11kb without dependencies) it was designed to be modular, so if you do not need ECC support, do not include elliptic as a dependency and it will not be loaded. We have done no security review or take a position on the security of these third-party libraries. We have no control over the corresponding implementation and what it does, for example, it may not use even if it is available and the mechanism it uses to gather randomness may be both insecure and weak. Webcrypto-liner will always try to use a native implementation of webcrypto, or a prefixed version of webcrypto, before it falls back to a Javascript implementation of a given algorithm. The libraries webcrypto-liner relies on include: PackageĪ performant JavaScript implementation of popular cryptographic utilities with performance in mind.įast Elliptic Curve Cryptography in plain javascriptĪ input validation layer for WebCrypto polyfills 1ġ This library is compiled into webcrypto-liner.
We strongly recommend you read " What’s wrong with in-browser cryptography?" before using this library. Intentionally webcrypto-liner does not implement any cryptography though it does consume libraries that do. Webcrypto-liner is a wrapper for WebCrypto designed to address these issues, at the same time it was designed to be modular so that it can also be used for testing the addition of new algorithms to WebCrypto in the future.

NOTE: If you are not familiar with how to use the various capabilities of WebCrypto see this great example page. Additionally, they do not always support the same algorithms, for example, Edge does not support SHA1 or ECC while both Firefox and Chrome do. Though WebCrypto is well supported across browsers, several browsers still have prefixed and buggy implementations. A polyfill for WebCrypto that "smooths out" the rough-edges in existing User Agent implementations.
