I have a small open source project and I am about to add some encryption to it. I am wondering if this will restrict where developers can contribute from. If so where are these laws so stringent?

Thanks ...

If I use the functions below the beginning of my original string turns into binary garbage after decryption. (This is not the usual problem of getting appended additional garbage, instead my string is altered.) According to the documentation, mcry...

I'm storing my passwords on a server, and, using nothing but HTML/JavaScript, I need to be able to take an input password, compute the hash, then compare against what's in my database via Ajax. As I'm using CouchDB, there's actually no server code, which is where I'd normally do such a calculation. Any kind of one way encryption woul...
Is there a way to encrypt/decrypt text (string form) in VB.net using another string as a key? Meaning, if one user encrypts using this key, the other user needs to decrypt using the same key?

AES and other modern encryption algorithm are considered strong and sometimes one can see quotes like "it's not recommended to use classic zip encryption since it is no longer considered strong". But is there a really non-linear difference between them? For example, if both produce sequences with high entropy, does it mean that with a ve...
