This option is available as single line option, select Download Certificate or Download Public OpenSSH Key from the actions Button in the line of the private Key Pair to be used for the connection to the sftp server. Furthermore, for usingpublic key authentication towards the sftp server, a private key pair with the alias id_rsa or id_dsa is required in the cloud integration tenants keystore. If you are using a different AWS SFTP endpoint, follow the same known host file configuration process shown in the previous SAP CPI known host file configuration. Is that correct? Else the only option is to get the broken connection fixed with the new key. To download entries from Keystore Monitor your user needs the Group Role AuthGroup.IntegrationDeveloper or Single Roles IntegrationOperationServer.read and NodeManager.read. You should not use username/password authentication to SFTP servers. Cloud integration needs the user name to connect to the sftp server. Can you please suggest how to address the issue.

The authentication is done with the id_rsa/id_dsa key with the user entered in User Name. the private SSH key can be generated in the keystore as described in the blog in chapter 'Create id_rsa/id_ecdsa in Keystore Monitor'. Does it mean that CPI only works with ssh/rsa key sizes that were just mentioned?

Mid-term we will offer dynamic setting of authentication option, then you can go with one channel and configure authentication dynamically. To create username- and password-based authentication, see AWS Transfer for SFTP for SAP file transfer workloads part 1. Any clue on why this error message is returned?

Do you see something for this call in the sftp server logs? With the June-2020 update the key pair for the connection to the sftp server can be chosen by defining the respective key alias in the sftp adapter configuration. thanks for the info, good that you got it working. If no knwon_hosts file is deployed yet on the tenant you have to create it as described below. Create this key pair in CPI keystore for the connection to the sftp server and use the same alias in the sftp adapter configuration at private key alias. Open Putty Key Gen. Click "Generate." Below is how the generated key will look like. Starting with the 8-June-2020 release, you can configure the SFTP adapter in Cloud Integration dynamically. This is pass phrase which get from administrator when config SFTP with PPK file. thanks for a detailed blog Mandy, br Vikas.

I downloaded the key with option Download Public OpenSSH Key and I created a new id_rsa. There are two options to store known hosts files in Cloud Integration: Can you suggest any publicly available SFTP server which can be used to test SFTP related iflows using CPI. Is it sftp sender or receiver? If it can not, does it is planned in the roadmap of future? Can any one please help me with public key username? For public key authentication at the sftp server the public key of the cloud integration tenants private key is needed in the sftp server. Once you have shared the password, you cannot make anyone to forget it again, so to remain secure, you would have to change it each time someone leaves the project, which is difficult and error-prone as stated above.
