Struct DecryptionContext 

pub struct DecryptionContext { /* private fields */ }

Holds the decrypted per-tablespace key and IV for page decryption.

Implementations

impl DecryptionContext

pub fn from_encryption_info( info: &EncryptionInfo, keyring: &Keyring, ) -> Result<Self, IdbError>

Build a decryption context from encryption info and a keyring.

Looks up the master key in the keyring using the server UUID and master key ID from the encryption info, then decrypts the tablespace key+IV using AES-256-ECB, and verifies the CRC32 checksum.

pub fn decrypt_page( &self, page_data: &mut [u8], page_size: usize, ) -> Result<bool, IdbError>

Decrypt an encrypted page in-place.

Decrypts bytes [38..page_size-8) using AES-256-CBC, then restores the original page type from the FIL header byte 26 (where MySQL saves it before overwriting with the encrypted page type).

Returns Ok(true) if the page was decrypted, Ok(false) if the page type is not an encrypted type and no decryption was needed.

pub fn is_encrypted_page(page_data: &[u8]) -> bool

Check if a page has an encrypted page type.
