Nodejs crypto vs python hashlib

由 北城余情 提交于 2019-12-07 12:21:00
问题 I'm trying to make a python function and a nodejs function compute the same hash. However, it seems like the binary that is outputted is different between nodejs crypto and python hashlib. The python I'm using is: hash = hashlib.sha512() hash.update(salt) hash.update(password.encode('utf8')) hash.digest() The node/coffeescript is: crypto.createHash('sha512').update(salt, 'binary').update(password, 'utf8').digest() These lines should produce the same result, but for some reason they don't.

Storing a SHA512 Password Hash in Database

问题 In my ASP.NET web app I'm hashing my user passwords with SHA512. Despite much SO'ing and Googling I'm unclear how I should be storing them in the database (SQL2005) - the code below shows the basics of how I'm creating the hash as a string and I'm currently inserting it into the database into a Char(88) column as that seems to be the length created consistently Is holding it as a String the best way to do it, if so will it always be 88 chars on a SHA512 (as I have seen some bizarre stuff on

HMAC SHA512 using CommonCrypto in Swift 3.1 [duplicate]

由 筅森魡賤 提交于 2019-12-06 14:58:34
问题 This question already has answers here : CommonHMAC in Swift (10 answers) Closed 2 years ago . I'm trying to encrypt data to send to the API. The API requires the data to be sent as hmac_sha512 encrypted hash. I've found various examples of how it possibly could have been done for sha1 and others (not sha512 ) and also in older versions of Swift. None of the examples that I tried work for swift 3.1 Any help in the right direction will be appreciated. Edit: In PHP, I successfully send it using

How do a use a SecureString to create a SHA1 or SHA512 Hash?

由 若如初见. 提交于 2019-12-06 06:33:48
I would like to use a SecureString varible within VB.NET and convert that to a SHA1 or SHA512 hash. How would I securely convert the SecureString to the Byte array that HashAlgorithm.ComputeHash will accept? What about that, if we avoid the only used String instance (output) and replace it with a character array. This would enable us to wipe this array after use: public static String SecureStringToMD5( SecureString password ) { int passwordLength = password.Length; char[] passwordChars = new char[passwordLength]; // Copy the password from SecureString to our char array IntPtr passwortPointer =

SHA 512 crypt output written with Python code is different from mkpasswd

PHP Openssl decrypt an AES Mysql Encryption

So i'm just doing some basic data encryption on my mysql tables. I followed the guidelines found here https://dev.mysql.com/doc/refman/5.6/en/encryption-functions.html#function_aes-encrypt But i'm running into an issue. While i know i can just use aes_decrypt in the mysql query to decrypt the data. I want to also have the ability for php to do so itself. I've gotten this part working. If MySQL does the very basic AES_ENCRYPTION like so INSERT INTO tablename (dataset) VALUES (AES_ENCRYPT('testvalue','mysecretphrase')) I'm able to decrypt this with php like so openssl_decrypt(base64_encode($dR[
