问题 I am using Jasypt APIs (version 1.9.2) for encryption and decryption. While listing the algorithms using the command line interface tool, I am getting the following list. listAlgorithms.bat PBE ALGORITHMS: [PBEWITHHMACSHA1ANDAES_128, PBEWITHHMACSHA1ANDAES_256, PBEWITHHMACSHA224ANDAES_128, PBEWITHHMACSHA224ANDAES_256, PBEWITHHMACSHA256ANDAES_128, PBEWITHHMACSHA256ANDAES_256, PBEWITHHMACSHA384ANDAES_128, PBEWITHHMACSHA384ANDAES_256, PBEWITHHMACSHA512ANDAES_128, PBEWITHHMACSHA512ANDAES_256,

问题 is there any default implementation for password history? i'm trying to implement that feature on my project with identity so i have added password history table which contain password hashes. when user change password usermanager generate hash for password. var passwordHash = _userManager.PasswordHasher.HashPassword(user, newPassword); if this hash does not inserted in password history table it allow to change password otherwise return error but the problem is each time when generating hash

问题 I have created a simple C# class library targetting .Net Framework 4.5.2 with one class using Visual Studio 2015 enterprise edition. Sample code: namespace PwdEncryptor { public class Class1 { public string Encrypt (string actualPassword) { return String.Concat(actualPassword, "Encrypt"); } } } I want to use this from my powerbuilder code on another system . Purpose of doing this is to have common code for encryption of password. Problem: I used it in my powerbuilder code by declaring in the

问题 I have a table: CREATE TABLE TempHashedValues( HashedValues varbinary(200) ) Now, I am inserting encrypted values to it using, so that could be used later: Insert into TempHashedValues values ( EncryptByPassPhrase('key', 'SecretEncoded' )) Now when I am trying to decrypt them using same key: Select TOP 1 DECRYPTBYPASSPHRASE('key',HashedValues) from TempHashedValues I am just getting the binary value back , not the value I encrypted !! What am I missing? 回答1: As stated here http://sqlity.net

问题 I am using spring security with BCrypt Password encoder for authentication. when i want to login, Spring security fetchs user data with JPA correctly but for checking raw password with encoded password it gives null string as encoded password to password encoder. spring security config : @Configuration public class SecurityConfig extends WebSecurityConfigurerAdapter { @Autowired @Qualifier("userDetailsServiceImpl") private UserDetailsService userDetailsService; @Bean public PasswordEncoder

问题 This problem is related to TOTP as specified in RFC6238 here: https://tools.ietf.org/html/rfc6238#section-1.2. I am to implement the RFC6238 to generate a 10-digit TOTP password, which will be used in a POST request later on. The sample input and output for the TOTP is supposed to be like this: Sample Input: Shared key: "ninja@example.comHDECHALLENGE003" (without double quotes) Hash function used: HMAC-SHA-512 T0 = 0, Timestep = 30 seconds (as per specified in RFC6238) Expected TOTP of 10

问题 I have implemented Spring security on my struts2 application and it perfectly works, but it runs into error java.lang.NullPointerException on line 3. Although it seems passwordEncoder configuration works as by adding those I cant login with a plain text password any more. <authentication-manager> <authentication-provider> <password-encoder ref="passwordEncoder"/> <jdbc-user-service data-source-ref="dataSource" users-by-username-query=" select username,password,enabled from Users where

问题 I am working on a project where I had got my password field value's hashCode and stored that hashCode in DB for security purposes.Now I want to recover the password from the hashCode.How can I do it? Is it possible to get the String value back from the hashCode ?If it is not, can anyone suggest me a better way to store my password in anyother format? 回答1: You know that several objects can have same hash(), as it mentioned in java doc for Object.hashCode() It is not required that if two
