- Rust `cryptoki` doesn't know about CKO_PROFILE objects. - The `sc-hsm-embedded` PKCS#11 provider does not expose the profile object, however it also doesn't support CKO_DATA objects. It does support RSA3K keys, which were used in the ES chip. - The `opensc-pkcs11` provider does expose the profile object and does support CKO_DATA objects. It does _not_ support RSA3K keys. This hack adds support to `cryptoki` for the profile object (e.g. it simply recognizes the object). This allows the use of the `opensc-pkcs11` provider which will permit using CKO_DATA objects from `hsmtool`. Signed-off-by: Chris Frantz <[email protected]> (cherry picked from commit 7c0210c)
1. Add support for `CKO_DATA` objects (aka "elementary files"). Signed-off-by: Chris Frantz <[email protected]> (cherry picked from commit bdab355)
1. Create an `SpxInterace` trait. 2. Refactor the acorn library to implement the trait. Signed-off-by: Chris Frantz <[email protected]> (cherry picked from commit 54e4af9)
Create a SPHINCS+ implementation that uses key material from PKCS#11 Elementary Files (aka CKO_DATA objects). This implementation stores key material on a secure token, and loads the key material to perform the sphincs+ operations. This is not as secure as signing within an HSM security boundary, but it provides token-protected storage for key material when an HSM-based implementation is not available. Signed-off-by: Chris Frantz <[email protected]> (cherry picked from commit 6a0c877)
Prepare data according to the input format (plain-text, sha256-hash, etc) and the sphincs+ signing domain (none, pure, prehashedsha256). Signed-off-by: Chris Frantz <[email protected]> (cherry picked from commit fbd2358)
