RSA Keys Generator

secondlife · Sep 4, 2019

Hi guys!

Can anyone who has some knowledge about RSA keys try to help me with this problem?

Is it possible to generate new unique RSA Keys for use on my server? I know how to change RSA on client (HexEdit) and server (Sources/ServerSide)

But my question is related to how it is possible to generate new keys that are "unique" for my client.

I've tried it with openssl, but the key format has nothing like the keys used in otservers.
OTServer format (look that - there are only numbers):

Code:

std::clog << ">> Loading RSA key" << std::endl;
    const char* p("14299623962416399520070177382898895550795403345466153217470516082934737582776038882967213386204600674145392845853859217990626450972452084065728686565928113");
    const char* q("7630979195970404721891201847792002125535401292779123937207447574596692788513647179235335529307251350570728407373705564708871762033017096809910315212884101");
    const char* d("46730330223584118622160180015036832148732986808519344675210555262940258739805766860224610646919605860206328024326703361630109888417839241959507572247284807035235569619173792292786907845791904955103601652822519121908367187885509270025388641700821735345222087940578381210879116823013776808975766851829020659073");

OpenSSL is like this (512bit):

Generally, p is prime1, q is prime2, d is privateExponent. You just need to conver the numbers from hex to decimal.

otland.net

That tutorial generates a really weak key though. But yeah you can use it and just generate one with a higher number of bits instead.
But in total, this is an issue you can solve by googling once. It takes you 2min to google and at least 2 hours until someone answeres here with a half way competent answer.

Generating keys using OpenSSL

For example here.
If you wanna know how RSA works itself, try this.

Cryptography - An Introduction

Cryptography Basics Since I see lots of wrong assumptions about what IT-Security actually is and how it is practiced i thought I'd write a "small" thread on the topic to help you make your OT and personal data more secure. Please be aware that i will just talk about basics and not go deeper...

Generally, p is prime1, q is prime2, d is privateExponent. You just need to conver the numbers from hex to decimal.

I hope you are not suggesting he uses the one you generated for him. That would not just be stupid but reckless. That would destroy the whole purpose of asymmetric encryption. He might as well not encrypt at all then.

Can you try following those steps?

[Tutorial] Generate RSA keys

After recent changes to tfs 1.3 by @Lordfire the rsa private key is now loaded from PEM file & it might be a bit confusing for some to generate custom rsa This tutorial requires openssl to be installed on your system. Debian & Ubuntu have it pre-installed. First generate your private key...

otland.net

Thanks for the reply, guy. Had already seen but this topic does not help me at the moment.

-----END RSA PRIVATE KEY-----

Generally, p is prime1, q is prime2, d is privateExponent. You just need to conver the numbers from hex to decimal.

Thanks so much for the reply @Don Daniello. I was able to execute openssl code perfectly. Now i am converting hex to decimal.

Another question.. On the client (Client Side) which RSA value should be added? d value?
Tks again!

On the client side you are using the "modulus" (n) and the publicExponent, which is typically always 65537. Those two make up the "public" part of the key.

Don Daniello, sorry to take your time again. It just didn't work

Look.. regarding converting from HEX to DECIMAL .. should i need convert each value one by one? example:

Code:

HEX = 69:26:eb:5c:63:9c:eb:c1:b7:7a:98:b1:9d:9c:83:

Staying:

Code:

DECIMAL = 105:38:235:92:99:156:235:193:183:122:152:177:157:156:131

And after removing the ":" tabs

Code:

105382359299156235193183122152177157156131

(Ofc i would do that for all HEX lines)

Or i must convert as follows:

Code:

HEX = 69:26:eb:5c:63:9c:eb:c1:b7:7a:98:b1:9d:9c:83:

being able to group all values and remove sep ":" = 6926eb5c639cebc1b77a98b19d9c83

and add to a HEX converter, getting:

Code:

545980548922332114411686556610698371

Many thanks again!!

How can I obtain the raw decimal value of an RSA key's modulus?

So maybe I'm thinking about this too hard, or maybe I'm missing a piece of information. We'll use Google for this example. Say I wanted to obtain the modulus of Google's current public key. Well I...

crypto.stackexchange.com

This looks like a good resource.

Hello, would you give an example of how the otclient module const.lua should look like? because if i convert all the hexas, i get 4 lines, and there are 5 lines in my OTSERV_RSA...

Also, once i compiled my server with the new RSA's, without editing my module in client side, i tried to connect to my server (local) and the server shutdown lol, when i changed the rsa in const.lua on my client, server don't shutdown but i get error connection (ERROR 2)
