password-encryption

I have some problems with encoding passwords,how can I do it. Type of encoding md5 digest(data text, type text) returns bytea; CREATE OR REPLACE FUNCTION md(bytea) returns text AS $$ SELECT encode(digest($1, 'sha1'), 'md5') $$ LANGUAGE SQL STRICT IMMUTABLE; INSERT INTO "login"(login, password, employee_id) VALUES ( 'email',crypt('password', md('md5')), 1); *** Error ** * ERROR: syntax error at or near "digest" SQL state: 42601 Character: 1 digest(data text, type text) returns bytea; is not valid syntax. I recommend using bcrypt instead. No additional function definitions are required: INSERT

I want to keep encoded password in my below mentioned springApplicationContext.xml Is there any way to achieve this? presently I have configured all properties using property-placeholder as shown below but the raw password is still open in my database.properties springApplicationContext.xml <beans:bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <beans:property name="driverClassName"><beans:value>${db.driverClassName}</beans:value></beans:property> <beans:property name="url"><beans:value>${db.url}</beans:value></beans:property> <beans:property name=

I'm doing an application for school and I'm in need of help in encrypting passwords when inserting them into my users database.I'm programming in c# programming language and i'm using MS server 2008 R2 for manipulating my database. I'm thinking of doing a HASH encryption and I would love if someone helped me out. Here's my code for inserting data into database : using (SqlConnection con = new SqlConnection("Data Source=HRC0;Initial Catalog=users;Integrated Security=True")) //MLHIDE using (SqlCommand sc = new SqlCommand("if NOT exists (select * from users where UserName = @username) insert into

I have been following a tutorial in order to create a login for an Android based application, however after encrypting the passwords I am unable to get authenticate users. I have been searching for a solution to the problem for a few days now and still no luck. I am hoping that it is something simple that I have missed. Tutorial playlist on YouTube There are also loads of people in the comments that have had the same issue as me on Video 6 (Last video in the playlist). GitHub Repository for tutorial Any support would be greatly appreciated and thank you in advanced! Register.php <?php require(

My first question is, I've heard that hashing the string 2 times (e.g. sha1(sha1(password)) ), because the second hash has a fixed length, is it true?? My the second question is, which is safer? (var1 and var2 are 2 strings): sha1(var1 + sha1(var2)) sha1(var1 + var2) If it is the 1st one, is it worth the performance cost? By hashing the string twice, you are increasing the risk of collisions, which is bad security-wise. Instead of having an infinite amount of inputs leading to 2 128 possible outputs, you will have 2 128 possible inputs leading to maybe less than 2 128 outputs. Using salt and

I want to store some passwords on my database at server. The passwords should be recoverable, since I want to use them for a third-party api which needs the password. (So I can't use one-way methods like md5...) What is the best method to save passwords in database? Isn't there any better way than storing plain text? Eric J. AES is cryptographically sound and probably the most common encryption (as opposed to hashing) mechanism selected for new applications. Take care to generate a random initialization vector (IV) for each password that you encrypt, and store the Key and the IV separately

I am creating a database for a website I've just developed but I need to encrypt my passwords. I've never encrypted passwords before and I don't know how to do it, I've searched google and a lot of websites but all they do is confuse me. Here is my Sproc: CREATE TABLE USERS( Username Nvarchar(200) PRIMARY KEY NOT NULL, Password Nvarchar(200) NOT NULL, EmailPassword Nvarchar(200) NOT NULL, UsernamePassword Nvarchar(200) NOT NULL ) CREATE TABLE Usernames( Username Nvarchar(200) FOREIGN KEY(Username) REFERENCES USERS(Username), Usernames Nvarchar(300) NOT NULL, Description nvarchar(500) ) CREATE

I want to re-develop my existing project to laravel. In my old system I store password into md5. Now how can I convert it according to laravel hash method for existing user. Is there any direct method to do it? Is there any direct method to do it? No there's no direct method, but you could achieve that by overriding postLogin inside Auth/AuthController.php so it will check if the password is in md5 format then recrypt it with laravel hashing method else the user will connect normally, like : public function postLogin(Request $request) { $this->validate($request, [ 'login' => 'required',
