Struct matrix_sdk_crypto::AttachmentEncryptor [−][src]
pub struct AttachmentEncryptor<'a, R: Read + 'a> { /* fields omitted */ }
Expand description
A wrapper that transparently encrypts anything that implements Read
.
Implementations
Wrap the given reader encrypting all the data we read from it.
After all the reads are done, and all the data is encrypted that we wish
to encrypt a call to finish()
is necessary to get
the decryption key for the data.
Arguments
reader
- TheReader
that should be wrapped and enrypted.
Panics
Panics if we can’t generate enough random data to create a fresh encryption key.
Examples
let data = "Hello world".to_owned();
let mut cursor = Cursor::new(data.clone());
let mut encryptor = AttachmentEncryptor::new(&mut cursor);
let mut encrypted = Vec::new();
encryptor.read_to_end(&mut encrypted).unwrap();
let key = encryptor.finish();
Consume the encryptor and get the encryption key.
