Crate fiscal_crypto 

Digital-certificate loading and XML signing for Brazilian fiscal documents.

fiscal-crypto provides two capabilities:

• Certificate management — load a PKCS#12 .pfx file and extract the signing key plus X.509 certificate chain (certificate module).
• XML signing — produce <Signature> elements conforming to the NF-e / NFC-e XML-DSIG specification, using the loaded certificate.

Signature algorithms

By default, XML signing uses RSA-SHA1 for backwards compatibility. For ICP-Brasil v5 certificates or SEFAZs that reject SHA-1 (rejeição 297), use SignatureAlgorithm::Sha256 with the *_with_algorithm signing functions.

Re-exports
