Module rsa 

RSA signature verification: PKCS#1 v1.5 and RSA-PSS (RFC 8017).

Implements modular exponentiation and padding verification for rsa_pkcs1_sha256 / sha384 / sha512 and rsa_pss_* schemes.

Only verification is supported; signing is not implemented.

Structs

PublicKey

An RSA public key parsed from a PKCS#1 SubjectPublicKeyInfo DER blob.
