Creating an encryption key from several other keys and using hash functions. Ask Question. There are better ways to generate a key. $endgroup$ – Ramhound May 2 '12 at 18:50. Instead of concatening the (sub)keys and then md5 the result. $endgroup$ – akira May 4 '12 at 5:53. Add a comment. Serial Key Generator is application specially designed for software developers to help you protect your applications by serial key registration. Just in a few clicks you are able to generate serial keys and to use them inside your C#.NET, Visual Basic.NET, Delphi, C Builder and Java applications.Check out our video demonstrations for C#.NET and Java applications and you will see it is the.

MD5 hashes are also used to ensure the data integrity of files. Because the MD5 hash algorithm always produces the same output for the same given input, users can compare a hash of the source file with a newly created hash of the destination file to check that it is intact and unmodified.

Password Algorithm Identifiers

You specify the algorithms configuration for your site in the /etc/security/policy.conf file. In the policy.conf file,the algorithms are named by their identifier, as shown in the following table.

Table 2–1 Password Encryption Algorithms

Identifier	Description	Algorithm Man Page
1	The MD5 algorithm that is compatible with MD5 algorithms on BSDand Linux systems.
2a	The Blowfish algorithm that is compatible with the Blowfish algorithmon BSD systems.
md5	The Sun MD5 algorithm, which is considered stronger than the BSDand Linux version of MD5.
5	The SHA256 algorithm. SHA stands for Secure Hash Algorithm. Thisalgorithm is a member of the SHA-2 family. SHA256 supports 255-character passwords.
6	The SHA512 algorithm.
__unix__	The traditional UNIX encryption algorithm. Thisalgorithm is the default module in the policy.conf file.

Algorithms Configuration in the policy.conf File

The following shows the default algorithms configuration in the policy.conf file:

When you change the value for CRYPT_DEFAULT, the passwords of new users are encrypted with the algorithm thatis associated with the new value. When current users change their passwords,how their old password was encrypted affects which algorithm is used to encryptthe new password.

For example, assume that CRYPT_ALGORITHMS_ALLOW=1,2a,md5,5,6 and CRYPT_DEFAULT=1. Stellar phoenix key generator mac. The following table shows which algorithm wouldbe used to generate the encrypted password.

Identifier = Password Algorithm		Explanation
Initial Password	Changed Password
1 = crypt_bsdmd5	Uses same algorithm	The 1 identifier is also the value of CRYPT_DEFAULT. The user's password continues to be encrypted with the crypt_bsdmd5 algorithm.
2a = crypt_bsdbf	Uses same algorithm	The 2a identifier is in the CRYPT_ALGORITHMS_ALLOW list. Therefore, the new password is encrypted with the crypt_bsbdf algorithm.
md5 = crypt_md5	Uses same algorithm	The md5 identifier is in the CRYPT_ALGORITHMS_ALLOW list. Therefore, the new password is encrypted with the crypt_md5 algorithm.
5 = crypt_sha256	Uses same algorithm	The 5 identifier is in the CRYPT_ALGORITHMS_ALLOW list. Therefore, the new password is encrypted with the crypt_sha256 algorithm.
6 = crypt_sha512	Uses same algorithm	The 6 identifier is in the CRYPT_ALGORITHMS_ALLOW list. Therefore, the new password is encrypted with the crypt_sha512 algorithm.
__unix__ = crypt_unix	Uses crypt_bsdmd5 algorithm	The __unix__ identifier is not in the CRYPT_ALGORITHMS_ALLOW list. Therefore, the crypt_unix algorithm cannotbe used. The new password is encrypted with the CRYPT_DEFAULT algorithm.
