+/**
+ * PKCS#8 Formatted RSA Key Handler
+ *
+ * PHP version 5
+ *
+ * Used by PHP's openssl_public_encrypt() and openssl's rsautl (when -pubin is set)
+ *
+ * Processes keys with the following headers:
+ *
+ * -----BEGIN ENCRYPTED PRIVATE KEY-----
+ * -----BEGIN PRIVATE KEY-----
+ * -----BEGIN PUBLIC KEY-----
+ *
+ * Analogous to ssh-keygen's pkcs8 format (as specified by -m). Although PKCS8
+ * is specific to private keys it's basically creating a DER-encoded wrapper
+ * for keys. This just extends that same concept to public keys (much like ssh-keygen)
