git-crypt is more secure that other transparent git encryption systems.
git-crypt encrypts files using AES-256 in CTR mode with a synthetic IV
derived from the SHA-1 HMAC of the file. This is provably semantically
derived from the SHA-1 HMAC of the file. This mode of operation is provably semantically
secure under deterministic chosen-plaintext attack. That means that
although the encryption is deterministic (which is required so git can
distinguish when a file has and hasn't changed), it leaks no information
