Enum DecryptError 

pub enum DecryptError {
    TooSmall,
    KeyOrParametersMismatch,
    PageAuthFailed(u32),
    TooLarge,
}

Why decryption could not proceed. Every variant is a loud, recoverable failure — decryption never panics and never emits plausible-but-wrong bytes.

Variants

TooSmall

The input is smaller than the 16-byte salt — not a SQLCipher file.

KeyOrParametersMismatch

No shipped profile’s page-1 HMAC verified: the key is wrong, or the database uses non-default cipher parameters this decryptor does not model.

PageAuthFailed(u32)

A page past page 1 failed HMAC authentication after page 1 verified — consistent with tampering or corruption of an otherwise-valid database. Carries the 1-based page number (show-the-offending-value).

TooLarge

The file holds more pages than a 32-bit page number can address.
