Oracle Encryption with key

this is kind of a general question. But if I use DBCM_CRYPTO to encrypt something in say AES256, is there any way to pass that encrypted data to someone who is not running Oracle, and have then un-encrypt it?

How to handle encryption key with a large development team?

If we have a large development team, say 100, and we would like to keep our encryption key hidden from developers who are not directly involved in the encryption module/algorithm, what are some best practices to keep this key as secret as possible while still allowing for development and debugging?

Public-private key pair handling on a Windows ecosystem

I’ve been thinking about how to architect an infrastructure for one of our business applications with the following requirement:

What encryption algorithm/package should I use in a betting game?

I have a betting type site where I publish a number (between 0-100) that is encrypted. Then after a period of time, I would review what the number is and prove it with a key to decrypt the encrypted number to prove that I’m not cheating. I also want it to be easily verifiable by an average user.

How do PGP and PEM differ?

Email messages are sent in plain text which means that the messages I send to Derpina are visible to anyone who somehow gets access to them while they are in transit.

How does eMail encryption work?

I have been going over YouTube watching videos on eMail encryption and everyone seems to explain it from a different perspective. Some do it for a CompTIA exam while others just provide a primer.
Here is what I understood:

How to access an encrypted INI file from C on an embedded system with little RAM

I want to encrypt an INI file using a Delphi program on a Windows PC.

How can I get my own encryption algorithm tested?

I’ve just developed a block cipher symmetric-key algorithm and I am using it in some of my products. I want to put it to real test.

Are python’s cryptographic modules good enough?

I mean, say you were writing professional grade software that would involve sensitive client information. (Take this in the context of me being an amateur programmer.)

Implementation ideas to store multiple files within a single file for faster access?

My requirement is to store a large number of files within a single file.The files stored could be anything like images, videos or simple text files as well. I want some ideas to implement the same. I am thinking of implementing a file system within a file, but am not sure if its a good idea.
