Here's my code var hash : [CUnsignedChar] CC_SHA256(data.bytes, data.length, hash) var res : NSData = NSData.dataWithBytes(hash, length: CC_SHA256_DIGEST_LENGTH) it gives me error everything because swift cannot convert Int to CC_LONG , for example. 回答1: You have to convert explicitly between Int and CC_LONG , because Swift does not do implicit

Compare two hashed password using same salt using SHA-256 algorith in Java, Spring security?

I need some guidance on the scenario where I need to check the password coming from UI form (i.e, Authentication object) which I need to hashed using SHA-256 + constant salt (before making comparison) and password coming from DB (DB also has hashed password + salt) using Spring Security. I am looking to compare these two different hashed value generated using same SALT value. How we can do it in java? Could anyone please share me a sample code? jHilscher You could simply compare the two password strings passwordA.equals(passwordB) ... This has some security shortcomings: Passwords should not

I'm now attempting to secure my connections between my ELB and my backend NGINX servers on EC2 using HTTPS with a self-signed certificate. I've followed the documentation , but accessing the server over HTTPS results in a 408 HTTP timeout. I can't seem to get any debugging information to determine where things are failing. I've confirmed that the security groups permit connections between the ELB and NGINX on EC2. I've convirmed that the VPC allows traffic

At first I generated the key pair and gave the public key to CloudKit, no problem so far. I started to build the request header. According to the documentation it should look like this: X-Apple-CloudKit-Request-KeyID: [keyID] X

I would like to seek advice if my methods in hashing is sufficient or overkill for the task. Dim result As Byte() Dim mixer As String Try Dim sha As New SHA512CryptoServiceProvider mixer = txt_salt.Text.ToUpper + txt_pass.Text.Trim result = sha.ComputeHash(System.Text.Encoding.ASCII.GetBytes(mixer)) txt_sha.Text = Convert.ToBase64String(result) Catch ex As Exception MsgBox(ex.ToString) End Try Thanks. 回答1: It is insufficient.

SHA家族的五个算法,分别是SHA-1、SHA-224、SHA-256、SHA-384,和SHA-512,由美国国家安全局(NSA)所设计,并由美国国家标准与技术研究院(NIST)发布,是美国的政府标准。 哈希算法使用比较广泛,具体算法原理就不再赘述,这里只是记录一下C语言的源码和使用。 以下先是SHA1的算法 /* * FIPS - 180 - 1 compliant SHA - 1 implementation * * Copyright ( C ) 2006 - 2015 , ARM Limited , All Rights Reserved * SPDX - License - Identifier : Apache - 2.0 * * Licensed under the Apache License , Version 2.0 (the "License" ); you may * not use this file except in compliance with the License . * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS ,
