FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package mfa
nishadil\mfa
A php library for Multi-factor authentication (MFA). MFA also known as 2FA or two factor authentication.
What is TOTP
The TOTP algorithm follows an open standard documented in RFC 6238. The inputs include a shared secret key and the system time.
What is HOTP
HOTP stands for HMAC-based One-Time Password and is the original standard that TOTP was based on. Both methods use a secret key as one of the inputs, but while TOTP uses the system time for the other input, HOTP uses a counter, which increments with each new validation. With HOTP, both parties increment the counter and use that to compute the one-time password. The HOTP standard is documented in RFC 4226.
Installation
This library can be installed using Composer. To install, please use following command
How to use
Generate Secret Code
To create new secret code for user, call public static mathod Mfa::createSecretCode();
output:
Generate long Secret Code
By default, we defined secret code length to 16 char long. You can change it if you need to generate long code. Accepted values should be in integer and within range of 16 to 128.
eg: now we want to generate a 32 char long secret code. Mfa::setSecretCodeLength(32)->createSecretCode();
output:
Get TOTP from secret code
TOTP stands for Time-based One-Time Passwords and is a common form of Multi-factor authentication (MFA). To generate your TOTP based on your secret key and time you can call public static mathod Mfa::getTOTP( string $secretCode );
output:
Validate TOTP
To validate your TOTP based on your secret key and time you can call public static mathod Mfa::validateTOTP(string $secretCode, string $userProvided_otp);
output:
Get HOTP from secret code
HOTP stands for HMAC-based One-Time Password and is the original standard that TOTP was based on. To generate your HOTP based on your secret key and counter value to call public static mathod Mfa::getHOTP( string $secretCode, int $counter );
output:
Validate HOTP
To validate your HOTP based on your secret key and counter value call public static mathod Mfa::validateHOTP(string $secretCode, string $userProvided_otp, int $counter);
