Crate flamberge_crypto 

Shared cryptographic primitives for the Flamberge tool suite.

Two ciphers here are bespoke to the ebook-DRM world and are implemented from scratch (they exist in no crate): the PC1 / Pukall stream cipher used by Mobipocket, and the Topaz stream cipher. Everything else (AES, DES, RC4, digests, PBKDF2) is a thin wrapper over standard implementations.

See docs/DEDRM_SCHEMES.md §1 for the reference specification.

Re-exports

pub use error::CryptoError;

Modules

aes

AES wrappers (CBC / ECB / CTR), all no-padding.

crc32

CRC-32 variants used by the PID / key-derivation code.

des

Single-DES wrappers (eReader content, Kindle Android V2 obfuscation).

digest

Hash digests used across the key-derivation code (MD5, SHA-1, SHA-256).

error

kdf

Key-derivation helpers: HMAC-SHA256, PBKDF2-HMAC-SHA1, and PKCS#7 unpadding.

pc1

PC1 / Pukall Cipher 1 — the Mobipocket / Kindle stream cipher.

rc4

RC4 / ARC4 stream cipher (Adobe & B&N PDF per-object decryption).

rsa

RSA private-key operations for Adobe ADEPT (§7).

topaz

Topaz stream cipher (Amazon Kindle Topaz format).
