+# `rsa-export` is unmaintained
+
+This crate has been deprecated in favour of using the native support for exporting RSA keys into the standard PEM format.  
+See [docs.rs documentation].
+
+In addition to that, the operations in this crate (arithmetic and Base64 encoding) are not done in constant-time, 
+potentially [exposing the user to sidechannel attacks].
