scrypt

问题 I've been struggling with this for some time now, hopefully someone has done this before and can help me on my way. I went to the Firebase people to request the scrypt params in order to migrate our user authentication away from Firebase to our own server. Now I got those params, but I have no clue as how they should map towards the node scrypt package (https://www.npmjs.com/package/scrypt). The Firebase params are of the following format: hash_config: { algorithm: SCRYPT, base64_signer_key:

问题 I am trying to find a library to implement password hashing(with salt) using Scrypt algorithm. My question is similar to one already asked in stackoverflow (Hash password in Swift application) I have found following two libraries in swift and objective c respectively but the hash string generated from these is not matching with the one generated at server. Swift-Sodium (https://github.com/jedisct1/swift-sodium) NAChloride (https://github.com/gabriel/NAChloride) Can someone please help in

问题 For security purposes I will encrypt some data, including the user password in my application. My colleagues have chosen scrypt hashing algorithm, for a 64 bytes length, with a fixed seed, then converted to hex. Hashing " A12345678Z " leads to: 25fac84a1cc3a8f6706848d1016cfe7e9d3631691306dcacae68c11c7b54f0bf89e7a7fc51f7fcc19671775acb21c8d928c4c96bb66d915925de58b8b36ab251 Seed is “ HeanpyftAkWilfUd ”. On server, they are using this implementation : https://github.com/ricmoo/pyscrypt Example:

问题 I was trying to find a compare or verify function for node's built-in crypto module, specifically for scrypt, as most password-hashing modules I have used have such a function. Then, I discovered why this was an impossible task: All hashes generated with these algorithms using the same parameters generate the same string (technically buffer). This is the case for many of crypto 's hashing functions, including its pbkdf2 implementation. Why is this safe? Isn't the whole (modern) point of a

问题 It seems that Scrypt doesn't install on my machine. I've installed the version for Windows here. I used Visual Studio free edition, installed OpenSSL 32-bit, and compiled BCrypt with success; but SCrypt returns this error: > setup.py install running install running build running build_ext building 'scrypt' extension C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN\amd64\cl.exe /c /nologo /Ox /MD /W3 /GS- /DNDEBUG -DHAVE_CONFIG_H -Iscrypt-1.1.6 -Iscrypt-1.1.6/lib -Iscrypt-1.1.6/lib

问题 I have a database of legacy passwords that were salted and hashed using MD5. I would like to update the system so that the data is more secure. The first option is to transition the users to a new hashing scheme (Salt + Scrypt or PBKDF2 HMACSHA256) when they login and deactivate old users after a certain period of time so they have to use the password recovery feature which would automatically update their hash. Another option that would allow me to instantly upgrade everyone would be to take

问题 I´m trying to install the npm module scrypt. I know scrypt requires node-gyp, i installed it globally (several times). Also I know node-gyp requires python 2.7 and MS Build Tools. I installed the latest python 2.7 build and i installed MS Build Tools. I also tried with VS Community Edition 2017. I tried to repair and reinstall both. I also installed npm package windows-build-tools (several times) globally successful. But wenn i try npm i scrypt i got the following errors: C:\Program Files

问题 I'd like to store an scrypt-hashed password in a database. What is the maximum length I can expect? 回答1: According to https://github.com/wg/scrypt the output format is $s0$params$salt$key where: s0 denotes version 0 of the format, with 128-bit salt and 256-bit derived key. params is a 32-bit hex integer containing log2(N) (16 bits), r (8 bits), and p (8 bits). salt is the base64-encoded salt. key is the base64-encoded derived key. According to https://stackoverflow.com/a/13378842/14731 the

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 months ago . Someone asked about a JavaScript implementation of bCrypt a while back and appears to have written their own code to handle the implementation. Does anyone have an implementation of sCrypt in JavaScript? 回答1: The answer linked above points to a project that no longer exists. This project, however, is still

问题 I have searched all over Google and I can't find a code sample of Scrypt usage (for hashing a password) using the Cryptsharp library. Can you please provide a sample for hashing the password? 回答1: It's only a single call so I'll walk you through the parameters: key : this is your password, use UTF-8 encoding (without byte order mark) to encode your password into a byte array; salt : a string of secure random bytes stored with the result of the scrypt function, 16 bytes should be ample; cost :
