Primo.TOTP 1.0.4

About

Primo.TOTP is a set of ready-to-use activities for Primo RPA Studio designed to automate generation of Time-based One-Time Passwords (TOTP) according to RFC 6238. It addresses the need to generate one-time passwords for two-factor authentication (2FA) within automation workflows. Key features include: generating TOTP codes from Base32-encoded secrets, supporting multiple hash algorithms (SHA1, SHA256, SHA512), configurable digit count and time period. The package can be added to any Primo RPA Studio project via the built-in dependency manager.

How to Use

In Primo RPA studio, create a project that will be executed by Primo RPA robot. Install this package via the ".Dependencies → Manage Dependencies" menu; the "TOTP" node with package elements will appear in Elements tree.

There is one element in the package: "Generate OTP". This element generates a time-based one-time password from a Base32-encoded secret key.

The "Generate OTP" element has the following properties:

• Secret (required): Base32-encoded secret key
• Result: Variable to store the generated OTP code
• Digits: Number of digits in the OTP (default: 6)
• Period: Time period in seconds (default: 30)
• Algorithm: Hash algorithm - SHA1, SHA256, or SHA512 (default: SHA1)

In pure code projects use the "Generate OTP" element as follows:

//wf: [LTools.Common.Model.WorkflowData] parent
//secret: [String] Base32-encoded secret key (e.g., "TE5TPRIMOTOTPK3Y")
//resultVar: [String] Variable name to store the OTP

var totp = LTools.Common.Model.PrimoModel.Init(wf);
string otp = totp.GenerateOTP(secret, 6, 30, "SHA1");

Pure code for direct TOTP generation:

//secret - [String] Base32-encoded secret key
//digits - [Int32] Number of digits (default: 6)
//period - [Int32] Time period in seconds (default: 30)
//algorithm - [String] Hash algorithm: "SHA1", "SHA256", or "SHA512"

Primo.TOTP.Generator.Elements.WfGenerateOtp totp =
    new Primo.TOTP.Generator.Elements.WfGenerateOtp(container);
string code = WfGenerateOtp.GenerateTotp(secret, digits, period, OtpAlgorithm.SHA1);
