ECC Encryption / Decryption

[Sanath Prasanna]

Tx Jesper for your kind response.  Here attached my sample test file &
following one is not working. That is the expected other Encoding scheme.
(ShaXxxx)
EncryptMsg = public_key:encrypt_private(Msg, ECPublicKey), (line 64)
Can you give some guide to over come this ?
br,
Robert
