High-level decryption facade.

Core API: decrypt(password, input, output)? for full file handling. Helpers: read_file_version, extract_session_data, StreamConfig for custom flows.

Enums

StreamConfig

Functions

consume_all_extensions

Consume all v2+ extensions (zero-copy skip)

decrypt

Decrypt an Aescrypt file (v0–v3) — zero secret exposure, maximum security

decrypt_ciphertext_stream

extract_session_data

Extract session IV + key — secure from first byte

read_exact_span

Read exactly N bytes into a stack-allocated [u8; N].

read_file_version

Validate file magic "AES" + version byte (0–3 supported)

read_kdf_iterations

Read KDF iterations (v3+ only). Returns 0 for older versions.

read_reserved_modulo_byte

Read the reserved/modulo byte (v0–v2: modulo, v3: reserved)
