RSA (RFC 4716) Public key in RSAParameter dotNet c#

I try to decrypt message with RSACryptoServiceProvider and RSAParameters to store my key values (Modulus, Exponent, ...). But i don't know how to import a RFC 4716 key. (I tried lot of thing, convert into PEM format, extract Modulus and Exponent ... but no once work)

pub key file :

ssh-rsa AAAB3NzaC1yc2EAAAADAQABAAABAQC+YshbLzdlXXBjyj2DpbQYgBzw+CfBOM82pOxCpEH0LP275gvswfCAwv/QXETrDqhspJBDT4jR4EYtpvH/sC8KLs17q6m9q/5va2g5SP6QQlOxyuSvlTWPa10/sYpyE2zkkJ09Nrkaacoh5iEQjXEJWbPWPvMAO5FkFjGkfS+nZ7nCdI9LTzuy33/5Wi7EDquLzV+094/Dxt0z9HP+Y73gh/2ENA0QKyhj7Idmg2IlyPFKm/6QAMGiUdI/cJoGXylo88GR9kjCH41ZpovlIPczcvrM5uB/m8cQfyUivAhaN4377zpJSTzxMTJmfWhAol1WdJs+PSdzzvOlTK26PnYj test

Solution

  • One of solution i found is to use the XML key format from dotNet and use library to use it on Javascript
