- WLanguage properties that can be used with the SecurePassword type
SecurePassword (Variable type) In french: MotDePasseSécurisé
The SecurePassword type is a structured type used to obtain a secure, hashed and salted password. This type of variable can be used: - for 3-tier applications that handle items of type Password.
- to store a secure password (hashed and salted) in a binary memo or in an XML file.
oSP is SecurePassword
oSP.Hash = SP_SHA2_256
oSP.IterationCount = 10000
oSP.Size = 256
oSP = "hello"
Syntax
Declaring and initializing a secure password Hide the details
<Password name> is SecurePassword
<Password name>: Name of the SecurePassword variable to be declared. Properties WLanguage properties that can be used with the SecurePassword type The following properties can be used to define the characteristics of SecurePassword variables:
| | | | Property name | Type | Effect |
|---|
| Age | Duration | Time elapsed since the password was last changed. | | Content | Character string | Password. | | Derivation | Integer constant | Key derivation function used to hash the password: - SP_PBKDF2: Password-Based Key Derivation Function 2 (PBKDF2) is used.
PBKDF2 is a key derivation function that takes the following parameters: - the password,
- a hash algorithm (SHA256, SHA512, etc.),
- a salt (randomly generated). Salts are used to prevent rainbow table attacks.
- a number of iterations. This number of iterations increases the time it takes to generate/compare a password and prevents attackers from testing millions of passwords in a short time. Thus, the time it would take to generate/compare a password is so long that it becomes impossible to try many combinations.
| | Hash | Integer constant | Salting algorithm: - SP_SHA2_256: Secure Hash Algorithm 256 (SHA-256) is used.
- SP_SHA2_512: Secure Hash Algorithm 512 (SHA-512) is used.
- SP_SHA3_256: Secure Hash Algorithm 3-256 (SHA-3 256) is used.
- SP_SHA3_512: Secure Hash Algorithm 3-512 (SHA-3 512) is used.
| | IterationCount | Integer | Number of iterations of the hash algorithm used. It is recommended to set a value between 10,000 and 30,000 | | Length | Integer | Hash output length (in bits). The key must be a multiple of 8, greater than 160 bits and less than 2048 bits. It is recommended to use a 256 or 512-bit key. |
