What encryption methods can be used with SFTP of FTP connector?

Question.

I would like to connect to an FTP server using SFTP with FTP connector.
What encryption formats of a private key can be used in this case?

Answer

You can use the following two encryption formats:

• RSA
• DSA

-Note

• Secret keys in binary format are not supported.
• Private keys with passphrases can also be used with the FTP connector, but the only supported encryption algorithm is DES-EDE3-CBC in this case.
• The private key you import must explicitly indicate the encryption format in its header.
  For example, if you are using RSA, your private key should begin with a header like the following:
  -----BEGIN RSA PRIVATE KEY-----
