Encrypt with public key:

openssl rsautl -encrypt -inkey public.pem -pubin -in xml.file -out encrypted.enc

Decrypt with private key:

openssl rsautl -decrypt -inkey private.pem -in encrypted.enc -out xml.txt

I think what you are looking for is this:

  1. If you have a PEM encoded key:

    openssl pkeyutl -encrypt -in FileToEncrypt -out EncryptedData.enc -inkey ThePathToYourPublicKey -keyform PEM

    If you have a DER encoded key:

    openssl pkeyutl -encrypt -in FileToEncrypt -out EncryptedData.enc -inkey ThePathToYourPublicKey -keyform DER

  2. You then decrypt with:

    openssl pkeyutl -decrypt -in EncryptedData.enc -out DecryptedFile -inkey ThePathToYourPrivateKey

For more information about this you can consult openssl's pkeyutil documentation.

If you want to use S/MIME packaging (a standard used to encrypt/decrypt/sign e-mails), see openssl's smime documentation.
