The MD5 message-digest algorithm is a widely used cryptographic hash function producing a 128-bit (16-byte) hash value, typically expressed as a 32 digit hexadecimal number. MD5 has been utilized in a wide variety of security applications.
Password Encryption
- RSA public key signature algorithm. Key length: Can be set, 384 bits to 16,384 bits in 8-bit increments. Default key length: 1,024 bits. Signature conforms to PKCS #6. CALGSHA: SHA hashing algorithm. For more information, see Secure Hash Algorithm. CALGSHA1: Same as CALGSHA. For more information, see Secure Hash Algorithm. CALGSHA256: SHA.
- The Microsoft Corporation’s Windows Vista Enhanced Cryptographic Provider (RSAENH) is a FIPS 140-2 Level 1 compliant, software-based, cryptographic service provider. Like other cryptographic providers that ship with Microsoft Windows Vista SP1 and SP2, RSAENH encapsulates several.
- Valid values for this parameter vary, depending on the CSP that is used. For a list of default algorithms, see Remarks. If the type of hash algorithm is a keyed hash, such as the Hash-Based Message Authentication Code (HMAC) or Message Authentication Code (MAC) algorithm, the key for the hash is passed in this parameter. For nonkeyed.
Strong password encryptionprovides an early barrier against attack. Solaris software provides four passwordencryption algorithms. The two MD5 algorithmsand the Blowfish algorithm providemore robust password encryption than the UNIX algorithm.
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.

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. 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. |
