There is more to a bitcoin wallet than just the address itself. It also contains the public and private key for each of your bitcoin addresses. Your bitcoin private key is a randomly generated string (numbers and letters), allowing bitcoins to be spent. A private key is always mathematically related to the bitcoin wallet address, but is impossible to reverse engineer thanks to a strong encryption code base.
If you don’t back up your private key and you lose it, you can no longer access your bitcoin wallet to spend funds.

We’ll cover the most common operating systems below, but first, let’s explain some basics about private keys. What is a private key? All SSL Certificates require a private key to work. The private key is a separate file that’s used in the encryption/decryption of data sent between your server and the connecting clients. I'm looking for a java library or code to generate certificates, public and private keys on the fly without to use third party programs (such as openssl). I think something that is doeing keytool+openssl but from Java code. Consider a java servlet based web application secured with ssl and client authentification. Jul 23, 2011 The difference between Public key and Private Key is that if the public key is the locking key, then it can be used to send private communication (i.e. To preserve confidentiality) while If the private key is the locking key, then the system can be used to verify documents sent by the holder of the private key (i.e. To preserve authenticity). Traditionally, private keys on Linux-based operating systems (Ubuntu, Debian, CentOS, RedHat, etc.) are openssl generated keys with the crypto toolkit and saved into files with the.key or.pem extension. However, since specific extensions are not obligatory for simple text files on Linux systems, the private key code can be put into a file.
As mentioned, there is also a public key. This causes some confusion, as some people assume that a bitcoin wallet address and the public key are the same. That is not the case, but they are mathematically related. A bitcoin wallet address is a hashed version of your public key.

Every public key is 256 bits long — sorry, this is mathematical stuff — and the final hash (your wallet address) is 160 bits long. The public key is used to ensure you are the owner of an address that can receive funds. The public key is also mathematically derived from your private key, but using reverse mathematics to derive the private key would take the world’s most powerful supercomputer many trillion years to crack.

Besides these key pairs and a bitcoin wallet address, your bitcoin wallet also stores a separate log of all of your incoming and outgoing transactions. Every transaction linked to your address will be stored by the bitcoin wallet to give users an overview of their spending and receiving habits.
Last but not least, a bitcoin wallet also stores your user preferences. However, these preferences depend on which wallet type you’re using and on which platform. The Bitcoin Core client, for example, has very few preferences to tinker around with, making it less confusing for novice users to get the hang of it.
Your bitcoin wallet generates a “master” file where all of the preceding details are saved. For computer users, that file is called wallet.dat. It’s saved on a Windows machine, for example, in the C:UserYournameDocumentsAppDataRoamingBitcoinfolder. Make sure to create one or multiple backups of this wallet.dat file on other storage devices, such as a USB stick or memory card. The bitcoin wallet software will let you import a wallet.dat file in case your previous file is damaged or lost, restoring your previous settings, including any funds associated with your bitcoin wallet address.
