Issue/Introduction

Failed to import participant certificate with error: java.security.SignatureException: Signature does not match

Environment

All platforms

Resolution

- Please verify whether the root CA certificate is configured in the CA Store (BusinessConnect > System Settings > Certificate Store).

- This issue may also be caused due to the signature algorithm 'RSASSA-PSS' which is used to sign the certificates. RSASSA-PSS is a very old signature algorithm, and it is not supported for TLS 1.2 as well as the security library 'BouncyCastle' which is used in BusinessConnect 7.2.x. Hence, to resolve such issues, please ask the trading partner to provide new certificates that are signed with an SHA signature algorithm (for eg. SHA256withRSA) and try to import these certificates.
