crypt

问题 I am working on my authorization module in GoLang. Before we used PHP5 with the crypt function. The hash was generated like SHA-512: $6$rounds=5000$usesomesillystri$D4IrlXatmP7rx3P3InaxBeoomnAihCKRVQP22JZ6EY47Wc6BkroIuUUBOov1i.S5KPgErtP/EN5mcO.ChWQW21 And stored like that in the database. But now I need make it work also in GoLang. I have searched on Google and tried different things, such as: t512 := sha512_crypt.Crypt("rasmuslerdorf", "$6$usesomesillystringforsalt$") fmt.Printf("hash: %v\n"

问题 All the examples online show the use of crypt like this: $pass = crypt('something','$6$rounds=5000$anexamplestringforsalt$'); But everyone says that you are not supposed to define the rounds or the salt. So how should I use it? Also I am having a problem: when I run the code above, it only runs 50 rounds instead of 5000 rounds as if the system is stopping it. Any help will be greatly appreciated. //- Solution -// I have found some of these to be useful: For generating Salt: $salt = substr(str

问题 I have the following snippet of code: // bcrypt hash of 'password' $hash = '$2y$10$4u0cQ.WEnwHDo.C5Nl1vm.shKA0beQ32wqzphSfzklAq9OcDM2nLu'; if(password_verify('password', $hash)) { print_r('woohoo!'); } else { print_r('fubar'); } On one server it's working fine (woohoo!), on another it doesn't work. I've just put it up on codepad.org and it fails there too. The problem is (as can be see on that codepad page) that the hash computed by crypt is of length 13 instead of the required 60. I'm using

问题 I am using the below code that i found somewhere in the net and i am getting an error when i try to build it. The compilation is ok. Here is the error: /tmp/ccCnp11F.o: In function `main': crypt.c:(.text+0xf1): undefined reference to `crypt' collect2: ld returned 1 exit status and here is the code: #include <stdio.h> #include <time.h> #include <unistd.h> #include <crypt.h> int main() { unsigned long seed[2]; char salt[] = "$1$........"; const char *const seedchars = ".

问题 I used this Java function to create Key pairs. KeyPairGenerator keyGen = KeyPairGenerator.getInstance(keyAlgorithm); keyGen.initialize(numBits); KeyPair keyPair = keyGen.genKeyPair(); PrivateKey privateKey = keyPair.getPrivate(); PublicKey publicKey = keyPair.getPublic(); // Get the bytes of the public and private keys byte[] privateKeyBytes = privateKey.getEncoded(); byte[] publicKeyBytes = publicKey.getEncoded(); I got this as public key(similar to this.Not possible to paste here): 0��0 *�H

问题 I've spent all night researching this without a solution. I'm trying to verify the digital signature of a file in the drives folder (C:\Windows\System32\drivers*.sys) pick whatever one you want. I know that the code is correct because if you move the file from that folder to C:\ the test works. WinVerifyTrust gives error 80092003 http://pastebin.com/nLR7rvZe CryptQueryObject gives error 80092009 http://pastebin.com/45Ra6eL4 What's the deal? 回答1: 0x80092003 = CRYPT_E_FILE_ERROR = An error

问题 A former developer used the PHP hash() function with the SHA256 algorithm to store password hashes. To improve the security of the system, I'd like to start using crypt() with the Blowfish algorithm (unfortunately we don't have PHP 5.5 and thus password_hash() is not available). Since SHA256 is a non-reversible hashing algorithm, is there a way to start using crypt() with the salted passwords without asking everyone to reset their password? 回答1: You should use the compatibility library then.

问题 I want to use the crypt_r function on Mac OS X 10.8.2 #define _GNU_SOURCE #include <crypt.h> produces crypt.h: No such file or directory Where can I get the crypt.h file from? Or am I including it wrong? Edited question - concrete example #include <unistd.h> #include <stdlib.h> int main(){ struct crypt_data * data = (struct crypt_data *) malloc(sizeof(struct crypt_data)); char * testhash; testhash = crypt_r("string", "sa", data); free(data); return 0; } produces gcc test.c -Wall test.c: In
