Adobe Campaign Classic v7: Error loading private key file: permission denied

Ensure you are on an earlier version of Snowflake ODBC driver such as 2.x.x or specifically tested versions like 2.25.xx. To check what version of the Snowflake ODBC driver you are on, refer to this Snowflake community post: How To Verify your Snowflake driver or connector version.
Snowflake ODBC driver versions 3.0.1 and above may cause issues due to changes in supported encryption algorithms after updating OpenSSL from version 1.1.1 to 3.x.x. When OpenSSL version was updated from 1.1.1 to 3.0.9 in version 3.0.1, deprecated encryption algorithms from the previous OpenSSL library version were no longer supported. Refer to this Snowflake community post ODBC Driver Release Notes for more details.

If you are on an appropriate version of Snowflake ODBC, try step 2.

1. Generate new RSA keys. Example command for generating RSA keys:

   openssl genrsa 2048 | openssl pkcs8 -topk8 -inform PEM -out rsa_key.p8
   The keys should be generated using an OpenSSL version compatible with your current setup (e.g., OpenSSL 1.x). So, if the Snowflake ODBC version is 3.x.x, the OpenSSL version must also be 3.x.x; otherwise, key-pair authentication fails. If you use a version lower than 3.x.x, such as 2.x.x, then you should use older OpenSSL versions, such as 1.x.x, to generate the key-pair.

Update your external account settings within Adobe Campaign Classic ensuring the Unicode data  checkbox is selected when configuring username/password combinations.

Verify permissions for accessing and reading private key files on your server where Adobe Campaign runs. For steps, refer to Snowflake: Key-pair authentication and key-pair rotation.
