How is hyperledger fabric security?

for a project of mine i wanted to know exactly how hyperledger fabric works exactly.

There is no shortage of documentation on how you can use this technology, I am really glad for developpers around there but i'm not a developper, I have to understand exactly what kind of algorithm are used in order to justify if we consider this technology safe or not. I obviously already know that it's probably safe, but it's not really enough for me to know that.

And while doc regarding usages and all are easy to find, finding doc on how it works in the background, and what kind of algorithm are used, is harder.

Nothing is stated regarding cryptographic algorithm in the official github documentation, as far as i know, and the only tiny bit of crypto that i found was on actual code from github, the internal part. I can more or less search what I want there, but I'm really in need of a technical documentation that i can quote and I just don't find it.

If you have some links to a technical doc, please let me know, in short what i search :

• Details on blockchain storage

• Cryptography behind hyperledger fabric, what kind of hash fonction it use ?

• Exactly what forms have data in the blockchain, what format ?

I'm here if I weren't clear about what i need. Not a native english speaker so if I wrote some mistake I hope it was bearable

Edit : now that i have more or less my solution, i'll share one more helpful link related to the documentation that i found, who talk about how tls is used with fabric.
