This answer is based on the stateless approach and therefore it doesn’t talk about the traditional session management You have asked two altogether different questions: Shopping cart – which is more related to business functionality OAuth 2 & JWT – which is related to security and authentication As an user of an ecommerce website, I’d … Read more
UPDATE July 21st, 2012 Google Analytics API V3 now supports OAuth2 tokens returned by a .p12-signed JWT request. That is, we can now use the Analytics API w/ service accounts. Currently pulling 4 years of day-by-day metrics, just for the hell of it. Here’s a quick ‘n’ dirty step-by-step: Go to the Google API Console … Read more
I’m the author of a node library that handles authentication in quite some depth, express-stormpath, so I’ll chime in with some information here. First off, JWTs are typically NOT encrypted. While there is a way to encrypt JWTs (see: JWEs), this is not very common in practice for many reasons. Next up, any form of … Read more
It doesn’t matter if the token was created on another server. You can still verify it if you have the right secret key and algorithm. Implementation with jsonwebtoken module client const {token} = sessionStorage; const socket = io.connect(‘http://localhost:3000’, { query: {token} }); Server const io = require(‘socket.io’)(); const jwt = require(‘jsonwebtoken’); io.use(function(socket, next){ if (socket.handshake.query … Read more
It can be safe under the following circumstances: the JWT is one-time time usage only the jti and exp claims are present in the token the receiver properly implements replay protection using jti and exp but in case it is used as a token that can repeatedly be used e.g. against an API then supplying … Read more
Thanks to jwilleke, I have got a solution. To verify the RS256 signature of a JWT, it is needed to use the RSAPKCS1SignatureDeformatter class and its VerifySignature method. Here is the exact code for my sample data: string tokenStr = “eyJraWQiOiIxZTlnZGs3IiwiYWxnIjoiUlMyNTYifQ.ewogImlzcyI6ICJodHRwOi8vc2VydmVyLmV4YW1wbGUuY29tIiwKICJzdWIiOiAiMjQ4Mjg5NzYxMDAxIiwKICJhdWQiOiAiczZCaGRSa3F0MyIsCiAibm9uY2UiOiAibi0wUzZfV3pBMk1qIiwKICJleHAiOiAxMzExMjgxOTcwLAogImlhdCI6IDEzMTEyODA5NzAsCiAiY19oYXNoIjogIkxEa3RLZG9RYWszUGswY25YeENsdEEiCn0.XW6uhdrkBgcGx6zVIrCiROpWURs-4goO1sKA4m9jhJIImiGg5muPUcNegx6sSv43c5DSn37sxCRrDZZm4ZPBKKgtYASMcE20SDgvYJdJS0cyuFw7Ijp_7WnIjcrl6B5cmoM6ylCvsLMwkoQAxVublMwH10oAxjzD6NEFsu9nipkszWhsPePf_rM4eMpkmCbTzume-fzZIi5VjdWGGEmzTg32h3jiex-r5WTHbj-u5HL7u_KP3rmbdYNzlzd1xWRYTUs4E8nOTgzAUwvwXkIQhOh5TPcSMBYy6X3E7-_gr9Ue6n4ND7hTFhtjYs3cjNKIA08qm5cpVYFMFMG6PkhzLQ”; string[] tokenParts = tokenStr.Split(‘.’); RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(); rsa.ImportParameters( new RSAParameters() { Modulus … Read more
The Spring security filter chain is a very complex and flexible engine. Key filters in the chain are (in the order) SecurityContextPersistenceFilter (restores Authentication from JSESSIONID) UsernamePasswordAuthenticationFilter (performs authentication) ExceptionTranslationFilter (catch security exceptions from FilterSecurityInterceptor) FilterSecurityInterceptor (may throw authentication and authorization exceptions) Looking at the current stable release 4.2.1 documentation, section 13.3 Filter Ordering you … Read more
Both choices refer to what algorithm the identity provider uses to sign the JWT. Signing is a cryptographic operation that generates a “signature” (part of the JWT) that the recipient of the token can validate to ensure that the token has not been tampered with. RS256 (RSA Signature with SHA-256) is an asymmetric algorithm, and … Read more
I found the solution, I just forgot to Cast the result: var stream = “[encoded jwt]”; var handler = new JwtSecurityTokenHandler(); var jsonToken = handler.ReadToken(stream); var tokenS = jsonToken as JwtSecurityToken; Or, without the cast: var token = “[encoded jwt]”; var handler = new JwtSecurityTokenHandler(); var jwtSecurityToken = handler.ReadJwtToken(token); I can get Claims using: var … Read more
Choosing the storage is more about trade-offs than trying to find a definitive best choice. Let’s go through a few options: Option 1 – Web Storage (localStorage or sessionStorage) Pros The browser will not automatically include anything from Web storage into HTTP requests making it not vulnerable to CSRF Can only be accessed by Javascript … Read more
