Enum EncryptionAlgorithm 

Source 
#[non_exhaustive]
pub enum EncryptionAlgorithm {
    Aes128,
    Aes256,
}
Expand description

Encryption algorithm.

§1.0 behaviour

Both Aes128 and Aes256 currently produce AES-256 output at the crypto layer because lopdf::aes256_encryption_state is the only AES helper exposed by our underlying lopdf fork today. This means selecting Aes128 yields stronger encryption than its name advertises, not weaker — safe but misleading. A true AES-128 path (PDF 1.6 V=4, R=4) lands in a post-1.0 follow-up.

Recommended: use Aes256 explicitly to match what actually happens.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Aes128

AES-128 selector. Currently routed to AES-256 — see the enum doc-comment.

§

Aes256

AES with 256-bit key (PDF 1.7 ext / 2.0). Recommended.
