Online SHA1 hash generator

I'm using SHA1 to encrypt some values like password.This is my code:

String passwd = Membership.GeneratePassword(10, 2);SHA1 sha = new SHA1CryptoServiceProvider();byte [] password = sha.ComputeHash(passwd);

But VS returns error, because passwd is a string.I have to store the password in a byte array, so is there a way to solve this?

I'm trying to get SHA-1 certificate for my Android Firebase project, following this instructions https://developers.google.com/android/guides/client-auth. When I enter this command in my cmd:

keytool -exportcert -list -v \-alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

I supposed to be asked to enter password, where I should enter android. But I am getting this:

So, what am I doing wrong here ?

We are busy implementing a payment provider (Ingenico) into our application. One of the security features implemented require to SHA1-hash our parameters. This SHA1-hash is checked against the SHA1-calculation on the payment provider's server.Unfortunately their documentation doesn't provide an example.

We are using the following code to calculate a SHA1 string (_shaSign) from a string (stringToHash).When running the code from our local environment, the SHA1 hashes on the local machine match the payment provider's hash.However, when we deploy the code on our test environment, the SHA1 mis-matches the payment provider's hash.

What could possible cause the different SHA1-hash after deployment on our server, using the following code to calculate the hash:

byte[] bytes = Encoding.UTF8.GetBytes(stringToHash);SHA1Managed sha1Managed = new SHA1Managed();byte[] hash = sha1Managed.ComputeHash(bytes);string hashString = "";foreach (byte x in hash){hashString += string.Format(CultureInfo.InvariantCulture, "{0:x2}", x);}_shaSign = hashString.ToUpper();

A possible example string we use to hash:

ACEPTURL=HTTP://WWW.GOOGLE.COMOURSECRETAMOUNT=12OURSECRETCURRENCY=EUROURSECRET

The string to hash will never contain whitespaces or newlines

--edit--To convince you guys; Tomorrow we'll post a hardcoded string example. Cannot do this ATM.

I have a PowerShell script that needs to access an online SHA1 conversion tool and generate a hash.

I used Fiddler to try and see what the call looks like when running the online tool with valid params, but my calls fail.

Here is my call:

Invoke-RestMethod -Method Post -Uri http://hash.online-convert.com/sha1-generator/formconvert/ -Body @{"hash_string" = $forClientHash}

Can anyone suggest a simple (i.e. tens of lines of code, not hundreds of lines) hash function written in (browser-compatible) JavaScript? Ideally I'd like something that, when passed a string as input, produces something similar to the 32 character hexadecimal string that's the typical output of MD5, SHA1, etc. It doesn't have to be cryptographically secure, just reasonably resistant to collisions. (My initial use case is URLs, but I'll probably want to use it on other strings in the future.)
