Implementations

impl UnsealingKey

pub fn scheme_name(&self) -> &'static str

Returns scheme name for this unsealing key.

pub fn unseal_bytes( &self, sealed_message: SealedMessage, ) -> Result<Vec<u8>, IesError>

Unseals the provided message using this unsealing key.

The message must have been sealed as bytes (i.e., using seal_bytes() or seal_bytes_with_associated_data() method), otherwise an error will be returned.

pub fn unseal_bytes_with_associated_data( &self, sealed_message: SealedMessage, associated_data: &[u8], ) -> Result<Vec<u8>, IesError>

Unseals the provided message using this unsealing key and returns the plaintext as bytes.

Errors

Returns an error if:

• The message was not sealed as bytes (i.e., if it was sealed using seal_elements() or seal_elements_with_associated_data())
• The scheme used to seal the message does not match this unsealing key’s scheme
• Decryption or authentication fails

pub fn unseal_elements( &self, sealed_message: SealedMessage, ) -> Result<Vec<BaseElement>, IesError>

Unseals the provided message using this unsealing key.

The message must have been sealed as elements (i.e., using seal_elements() or seal_elements_with_associated_data() method), otherwise an error will be returned.

pub fn unseal_elements_with_associated_data( &self, sealed_message: SealedMessage, associated_data: &[BaseElement], ) -> Result<Vec<BaseElement>, IesError>

Unseals the provided message using this unsealing key and returns the plaintext as field elements.

Errors

Returns an error if:

• The message was not sealed as elements (i.e., if it was sealed using seal_bytes() or seal_bytes_with_associated_data())
• The scheme used to seal the message does not match this unsealing key’s scheme
• Decryption or authentication fails
