Implementations

impl ChecksumAlgorithm

pub fn is_deprecated(&self) -> bool

Determines if a checksum algorithm is considered deprecated for security reasons.

Returns true for cryptographically unsafe algorithms that should be avoided. These algorithms are still supported for backwards compatibility but their use is strongly discouraged.

Currently deprecated algorithms:

• ChecksumAlgorithm::Md5: Vulnerable to collision attacks
• ChecksumAlgorithm::Sha1: Vulnerable to collision attacks

Examples

use alpm_types::ChecksumAlgorithm;

// Deprecated algorithms
assert!(ChecksumAlgorithm::Md5.is_deprecated());
assert!(ChecksumAlgorithm::Sha1.is_deprecated());

// Safe algorithms
assert!(!ChecksumAlgorithm::Sha256.is_deprecated());
assert!(!ChecksumAlgorithm::Blake2b512.is_deprecated());

pub fn non_deprecated_checksums(&self) -> Vec<ChecksumAlgorithm>

Returns a list of ChecksumAlgorithm variants that are not considered deprecated.
