The mirage-crypto repository provides DSA and RSA (PKCS1, PSS) signatures (https://mirage.github.io/mirage-crypto/doc/mirage-crypto-pk/Mirage_crypto_pk/index.html) - opam install mirage-crypto-pk (a fork of nocrypto).

The x509 uses mirage-crypto to verify and provision X.509 certificates (https://mirleft.github.io/ocaml-x509/doc/x509/X509/Signing_request/index.html#val-sign) opam install x509.
