Decrypting The Secrets: Inurl:security.txt And Its Rewarding Discoveries – Recently, I came across a use case while sharing important information with a team member. People are hesitant to share information in plain text and are concerned about encrypting messages online because of the risk of unknown threats.
Therefore, we considered creating our own in-house tool for plain text encryption and decryption.

Decrypting The Secrets: Inurl:security.txt And Its Rewarding Discoveries
Text Encryption Encryption is the process of converting a readable message into an unreadable form to prevent it from being read by unauthorized third parties.
Managing Secure Environment Variables With Secrets
Protect your text by encrypting and decrypting it with a key that no one else knows. Sensitive information is protected from unauthorized access and its confidentiality is fully controlled. Passwords keep conversations more private.
Sharing credentials such as AWS access/keys poses a significant challenge due to the risk of unauthorized access or data exfiltration. To address this challenge, we need a robust solution to ensure secure sharing of secrets.
The main goal of this solution is to provide users with a secure and reliable platform to exchange credentials in encrypted form, protecting sensitive information from potential threats. By implementing such a system, users can share their access credentials with confidence, knowing that their data is protected and the risk of unauthorized access is minimized.
This ensures the confidentiality and integrity of shared secrets, increasing the overall security and trust of the process.

The solution will provide an intuitive interface that allows users to securely encrypt their text. The encrypted text can then be shared with users who require encryption.
When users receive the ciphertext; they can easily decrypt it and use the portal to access the original content.
In this way, the platform ensures a transparent and user-friendly experience in the encryption and decryption process, and by enabling the exchange of sensitive information…
I’m a solution, design developer, operational security, passionate cloud consultant, Soln architect, specializing in networking; technologist and evangelist. HasMySecretLeaked helps security practitioners find out if their secrets have been leaked on GitHub.com. The first free service lets you check if. Users can easily query and protect their sensitive information by accessing GitGuardian’s vast database of more than 20 million discovered secrets, including their location on GitHub. This database contains code files dating back to 2017. Commits are compiled based on analysis of GitHub bullet points and issues.
Onboard Jims Collector
By opening this project to everyone; we recognize the responsibility and security challenges and seek to strengthen confidentiality protections wherever possible.
At GitGuardian, we are open and transparent. Accessibility; we believe in understandable safety. That’s why our goal is to make the protocol behind HasMySecretLeaked completely transparent. Our goal is to ensure that the service is resistant to malicious use while creating a trustworthy environment: with HasMySecretLeaked; rest assured that your secrets are safe: we can never access them, so you don’t need them. You don’t even have to do this. believe us!
To support these claims; this article describes the technical choices involved in creating a secure, practical, and user-friendly protocol. Without further ado, let’s get started.
HasMySecretLeaked is a very efficient REST API designed to accept string input. Its primary function is to answer the important question with 100% confidence: “Has my secret been revealed?”
What’s The Difference Between Encryption, Hashing, Encoding And Obfuscation?
As you can see, there’s a lot more going on behind the scenes. Understand how customers use this information and the API design decisions involved; let’s start with the insecure protocol implementation and build from there.
In the simplest way, the client sends its secret directly to the API. Issue: GitGuardian aka a service that can “see” user secrets in plain text is unacceptable.
How do users know if leaked credentials are in the repository without sharing their secrets with us?
Now assume the user sends a hashed version of their secret to the API. Since the secret is obfuscated and the service cannot undo the hash, it can certainly be improved. However, there are still privacy issues: by definition; if we have a hashed secret in our repository. This means that a plaintext version of it was ever publicly available on GitGuardian or indicates that it is known. In other words, users will reveal their secrets to us. I don’t accept that either.

In this method, the user sends only the first 5 characters, which are part of their secret. The service then retrieves all secrets that match those five characters. Ensure the response “bucket” is large enough; we protect user privacy by effectively blocking the original confidential service request.
💡Bucket size is essentially related to the length of the hash fragment: the longer the string, the smaller the bucket. Through real-world testing; currently we’ve found that a font size of 5 produces the best results. However, this is not set in stone and may be refined in the future.
We now have a secure service, but it’s missing an important feature. To prove a secret leak, a service must provide the location of the leaked URL. Without this feature, the utility of the service is almost nil.
How do you share a leaked URL while maintaining the privacy of the remaining URLs in the bucket?

The idea is simple: every item in the response container is now encrypted (using AES-GCM) using the (complete) hash value of the key as the key. This way we guarantee that only the consumer who knows the hash value (and therefore the secret) can decrypt the payload and retrieve the URL location.
This additional layer of encryption significantly reduces the risk of enumeration attacks. If it doesn’t exist, cybercriminals can access our entire database of hashed secrets and try any combination of five characters. However, there’s another potential combat scenario we’ll address shortly.
Now we’re faced with an accessibility problem: clients have to carefully parse each element individually so that they can find the content for which they have the key. There’s no quick way to quickly answer this important question: Has my secret been compromised?
The API now supports encrypted responses with a unique feature: prompts; which are basically hashes of hashes. This allows users to quickly calculate indices and determine whether responses are consistent. Simply put, they can quickly verify that their secret is in the repository. Digging into them requires encrypting a specific object using its secret raw hash value.

We have now set up a robust service that matches the example configuration provided at the beginning of this article. Let’s take a look at the previously mentioned attack scenario.
In this case, the attacker successfully compromised the hash secret repository using the same hash function used by our service. In this particular case, they are used to reverse hashes; you can use our service to collect all locations and find the unambiguous secret.
“pepper” is a string added to the hashing process to further improve security. Unlike “salt” which is specific to each element, “pepper” is universal.
Peppering makes our hash function unique and reduces the possibility of an attacker using an obsolete repository to reverse our hash value.

What if someone tried to guess the secret? Like passwords, many secrets are not randomly generated but created hastily. This is a pre-computed table used to reverse engineer cryptographic hash functions to check our service against a list of potentially vulnerable combinations, making it safe from attackers who might use “rainbow tables”.
Our trip ends here. To summarize, here are the main takeaways about HasMySecretLeaked.
We hope you’re ready to try HasMySecretLeaked and know that your secrets are safe.
As mentioned earlier, it’s important that users only share their hash secrets with us, and it’s equally important that GitGuardian designed the service to allow buckets to be very large. This approach ensures that GitGuardian has minimal knowledge of the user’s privacy.
What Is Symmetric And Asymmetric Encryption?
The challenge here is finding the balance: whether the bin is too small. GitGuardian can inadvertently gain too much insight into user privacy. In turn, containers that are too large can overload your API and overwhelm it. Determine the ideal prefix size; we need to estimate the possible number of secrets in the repository.
Our HMSL database now holds approximately 22 million unique secrets. The average value of a box and a bucket is 5 digits, to analyze the carton average of a single bucket, selected. If the distribution of the hash distribution is random and assuming a regular distribution, ensure that the number of seconds consistent with our agreement is less than 8.
It’s worth noting that over time, these buckets will become overwhelmed. If they are very large for our API, we can simply extend the average length by reducing the average bucket 1 by the number 1.
