Password Encryption

CRYPTVERIFYCONTEXT: This option is intended for applications that are using ephemeral keys, or applications that do not require access to persisted private keys, such as applications that perform only hashing, encryption, and digital signature verification. Only applications that create signatures or decrypt messages need access to a private key. Calculate MD5 by Windows CryptoAPI. GitHub Gist: instantly share code, notes, and snippets. Dec 24, 2015 Dear AutoIt communities, I wish to perform SHA-256 hashing with AutoIt. I noticed Help File shows the use of MD2, MD4, MD5, SHA1. To my knowledge, all of these aren't cryptographically secure anymore and SHA-2 (SHA-256, SHA-384, SHA-512) is the way to hash passwords.

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.

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. Bioshock infinite key generator download. 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.

Hello,
I want to generate a self signed certificate that uses 'sha1RSA' as signature algorithm.
I tried changing the default signature algorithm in OpenSSL config file (default_md), but there is no effect of the change on the certificate. The certificate shows 'md5RSA' as the signature algorithm.
Appreciate any help on how to achieve this.
Here are the detailed steps for your reference.
1) vi /etc/sfw/openssl/openssl.cnf
2) Original: default_md=md5. Modified this to default_md=sha1
3) Restarted the system
4) Gave the following commands
/usr/sfw/bin/openssl genrsa 1024 > host.key
chmod 400 host.key
/usr/sfw/bin/openssl req -new -x509 -days 365 -key host.key > host.cer
5) Irrespective of the value for 'default_md' in the openssl.cnf file, the signature algorithm is specified as 'md5RSA' in the certificate.
6) When I give the following command, the sha1 signature algorithm is used, however changing to the following command introduces lot of additional dependencies in my code.
/usr/sfw/bin/openssl req -new -x509 -sha1 -days 365 -key host.key > host.cer
7) Version of OpenSSL used is 0.9.7d 17 Mar 2004 (+ security patches to 2006-09-29) on a Solaris 10 machine with kernel patch id 137138-09.
8) I've performed a truss and dtrace to find the value read from the config file, but was not able to view the values for config parameters.
Thanks
Madhu
