How to use PKCS5_PBKDF2_HMAC_SHA1()

由 陌路散爱 提交于 2019-11-27 05:34:10
问题 I am trying to use PKCS5_PBKDF2_HMAC_SHA1() and below is my sample program. I wanted to make sure if my result of PKCS5_PBKDF2_HMAC_SHA1() is correct so I verified the same with the website http://anandam.name/pbkdf2/ and I see a different result. Am I using the API correctly? I am having doubts if I am passing salt value correctly. I have pasted my result and website result after the program. Please help me understand this. #include <stdio.h> #include <types.h> #include <string.h> #include

Is there a SQL implementation of PBKDF2?

由 一笑奈何 提交于 2019-11-27 01:46:17
Does anyone know of a SQL implementation of PBKDF2 ? (I'd rather not use an external library like, for example, ChillKat's ActiveX component.) PBKDF2 is built into the .NET framework as System.Security.Cryptography.Rfc2898DeriveBytes . It's straightforward to create a SQL CLR function that wraps a call to this class' GetBytes method. I realize you were looking for a solution that doesn't require an external library but at least this limits the dependency an assembly that simply wraps framework code. Here's a dramatically faster PBKDF2/PKCS #5/RFC2898 implementation of PBKDF2(HMAC-SHA-512...,

PBKDF2-HMAC-SHA2 test vectors

由 亡梦爱人 提交于 2019-11-27 01:19:55
问题 There are test vectors for PBKDF2-HMAC-SHA1 in RFC6070. There are test vectors for HMAC-SHA2 in RFC4231. But so far I haven't found test vectors for PBKDF2-HMAC-SHA2 anywhere. I'm most interested in SHA256, so I'll post some vectors I calculated with my implementation. I'd be happy if someone could verify/confirm them, or contribute their own. 回答1: I implemented PBKDF2 using the standard hashlib and hmac modules in Python and checked the output against both the RFC 6070 vectors and the

Reliable implementation of PBKDF2-HMAC-SHA256 for JAVA

由 孤者浪人 提交于 2019-11-26 19:06:16
问题 UPDATED 2019: Bouncycastle now support PBKDF2-HMAC-SHA256 since bouncycastle 1.60 Is there any reliable implementation of PBKDF2-HMAC-SHA256 for JAVA? I used to encrypt using bouncycastle but it does not provide PBKDF2WithHmacSHA256'. I do not want to write crypto module by myself. Could you recommend any alternative library or algorithm (if i can stick with bouncycastle) (here are the algorithms that bouncycastle supports) http://www.bouncycastle.org/specifications.html 回答1: Using

PBKDF2 with bouncycastle in Java

问题 I'm trying to securely store a password in a database and for that I chose to store its hash generated using the PBKDF2 function. I want to do this using the bouncy castle library but I don't know why I cannot get it to work by using the JCE interface... The problem is that generating the hash in 3 different modes: 1. using the PBKDF2WithHmacSHA1 secret key factory provided by sun 2. using the bouncy castle api directly 3. using the bouncy castle through JCE results in 2 distinct values: one

PBKDF2 function in Android

由 浪尽此生 提交于 2019-11-26 14:16:17
问题 Is there PBKDF2 implementation for Android. I am trying to derive a key using PBKDF2 function. I couldn't find an example to do so. 回答1: Free options would be: http://rtner.de/software/PBKDF2.html http://bouncycastle.org/ (that might be newer than some Android-bundled org.bouncycastle ) http://www.unwesen.de/2011/06/12/encryption-on-android-bouncycastle/ https://github.com/rtyley/spongycastle#readme IF a commercial component is an option see for example http://www.chilkatsoft.com/java

PBKDF2 using CommonCrypto on iOS

由 China☆狼群 提交于 2019-11-26 12:55:05
问题 I\'m trying to use CommonCrypto to generate keys using PBKDF2 but I can\'t seem to import CommonCrypto/CommonKeyDerivation.h , I just errors that it is not found. Any ideas? edit: I should probably mention I have already added the security framework and I can import all of the other CommonCrypto headers. 回答1: Here's how i generate AES256 keys. The only interesting this is that i get CommonCrypto to estimate for me how many rounds to use. It seems pretty straightforwards. #import <CommonCrypto
