ring encrypt data with an RSA key and OAEP padding

Comment

rsa_encrypt_oaep(pRsaKey,cPlainData[,nHashAlgorithm]) ---> return a string containing the OAEP encryption of cPlainData
        nHashAlgorithm indicates the hash algorithm to use for OAEP padding. If omited, SHA-1 is used by default.
        Possible values for nHashAlgorithm argument are:
         - $OSSL_HASH_MD5 which is equal to 0
         - $OSSL_HASH_SHA1 which is equal to 1
         - $OSSL_HASH_SHA256 which is equal to 2
         - $OSSL_HASH_SHA384 which is equal to 3
         - $OSSL_HASH_SHA512 which is equal to 4
