Vulnerability

Description

The rule "Encryption keys should be long enough" states that encryption keys used to protect sensitive data should be of a sufficient length to provide an adequate level of security. The longer the key, the more secure the data will be. Generally, the longer the key, the more difficult it is for an attacker to guess or crack the key. It is important to use strong encryption keys that are at least 128 bits long to ensure that the data is sufficiently protected.

Key Benefits

• Increased Security: Encryption keys should be long enough to make it difficult for an attacker to guess or brute force the key.
• Protection of Confidential Data: Encryption keys should be long enough to ensure that confidential data is kept secure and protected from unauthorized access.
• Improved Authentication: Encryption keys should be long enough to allow for stronger authentication and verification of users.
• Enhanced Privacy: Encryption keys should be long enough to provide a higher level of privacy for users.

Non-compliant Code Example

CrypterObject lnv_CrypterObject
lnv_CrypterObject = Create CrypterObject
// Generate the key
li_return = lnv_CrypterObject.AsymmetricGenerateKey(RSA!, 1024, lblb_privKey, lblb_pubKey) //Non compliant code(Key Length < 2048)

Compliant Code Example

CrypterObject lnv_CrypterObject
lnv_CrypterObject = Create CrypterObject
// Generate the key
li_return = lnv_CrypterObject.AsymmetricGenerateKey(RSA!, 2048, lblb_privKey, lblb_pubKey)//Compliant code (Key Length >= 2048, NIST recommendation)
