Enum EncryptionAlgorithm 

#[non_exhaustive]
pub enum EncryptionAlgorithm {
    NoPadding,
    Pkcs7,
    Unknown(u8),
}

The encryption algorithm used to encrypt the message.

Variants (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.

NoPadding

AES-GCM, using no padding

Pkcs7

AES-GCM, using PKCS7 padding

Unknown(u8)

Unknwon encryption version
