Windows XP was the first consumer-focused operating system to encrypt product keys and, in general, to take the product key process very seriously. So, unlike with older versions of Windows (a few sections below), Windows XP forces you to use those special product key finding software tools if you want to dig up your lost XP key. AES was designed to be efficient in both hardware and software, and supports a block length of 128 bits and key lengths of 128, 192, and 256 bits. How secure is AES encryption algorithm? AES encryption is used by U.S. For securing sensitive but unclassified material, so we can say it is enough secure. It would make sense that shorter than 512-bit key pairs cannot be generated. Public Key cryptography needs a longer key than symmetric key cryptography to sustain the same level of security. A 128-bit key pair is not recommended for public key cryptography.
On 64-bit Windows, portions of the registry entries are stored separately for 32-bit application and 64-bit applications and mapped into separate logical registry views using the registry redirector and registry reflection, because the 64-bit version of an application may use different registry keys and values than the 32-bit version. There are also shared registry keys that are not redirected or reflected.
The parent of each 64-bit registry node is the Image-Specific Node or ISN. The registry redirector transparently directs an application's registry access to the appropriate ISN subnode. Redirection subnodes in the registry tree are created automatically by the WOW64 component using the name Wow6432Node. As a result, it is essential not to name any registry key you create Wow6432Node.
The KEY_WOW64_64KEY and KEY_WOW64_32KEY flags enable explicit access to the 64-bit registry view and the 32-bit view, respectively. For more information, see Accessing an Alternate Registry View.
To disable and enable registry reflection for a particular key, use the RegDisableReflectionKey and RegEnableReflectionKey functions. Applications should disable reflection only for the registry keys that they create and not attempt to disable reflection for the predefined keys such as HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER. To determine which keys are on the reflection list, use the RegQueryReflectionKey function.

What is AES encryption?
It is a webtool to encrypt and decrypt text using AES encryption algorithm. You can chose 128, 192 or 256-bit long key size for encryption and decryption. The result of the process is downloadable in a text file.
How to use AES encryption?
If you want to encrypt a text put it in the white textarea above, set the key of the encryption then push the Encrypt button.
The result of the encryption will appear in base64 encoded to prevent character encoding problems.
If you want to decrypt a text be sure it is in base64 encoded and is encrypted with AES algorithm!
Put the encrypted text in the white textarea, set the key and push the Decrypt button.

What is AES encryption?
AES (acronym of Advanced Encryption Standard) is a symmetric encryption algorithm.
The algorithm was developed by two Belgian cryptographer Joan Daemen and Vincent Rijmen.
