Error: Algid Parse Error, Not a Sequence

Issue

While setting up the connector using the Certificate authentication mode, the following error appears:

Algid parse error, not a sequence.

Environment

• Connector: Anaplan
• Authentication mode: Certificate

Resolution

To resolve this issue, do the following:

1. Extract your private key by running the following OpenSSL command in your terminal window: openssl pkcs8 -topk8 -inform pem -in private_key.pem -outform pem -nocrypt -out private_pkcs8.pem
2. In the setup form, upload the private key in the Private Key file field.

Cause

This issue occurs when you provide a private key in the setup form that is encrypted in the Public-Key Cryptography Standards (PKCS) #1 format instead of the required PKCS #8 format.
