This allowed users to create invalid Ed25519 Extended Secret Keys with potentially cryptographically weak ECDSA Signatures. However we still allow to have an _unsafe_ version to construct a `SecretKeyExtended` from bytes without performing checks. This is in order to allow a compatibility path without breaking codes too much. allow the direct conversion from XPrv from ed25519_bip32 crates to pallas-crypto's SecretKeyExtended without performing the bit tweaks check While it is unsafe to call the SecretKeyExtended::from_bytes_unchecked (unsafe in the cryptographic sense, not in the rust memory management sense) we know this is going to be okay because the XPrv was already safely created. We previously removed the direct conversion of byte arrays into SecretKeyExtended This has been replaced with a `TryFrom` and a `from_bytes() -> Result<Self>` function. This allows us to perform the recovery of the wrapped private keys without losing the security of performing the checks of the validity of the Ed25519 Extended structure. This should be safe to use and shouldn't make incompatibilities because the Xprv was already checked for bit tweaks previously in the flow. add unsafe functions to leak the content of the SecretKey or SecretKeyExtended Remove the From implementation to convert Secret Keys into Bytes Instead prefer the explicit unsafe functions to leak the content of the keys temporarily remove the public access of the as_bytes function this is to prevent leaking the bytes of the private keys. |
