J.P. Morgan Host-to-Host has changed Certificate Authorities from Entrust to DigiCert. All new new certificates will now be issued by DigiCert. This will include new DigiCert Root and Intermediate certificates.
SFTP SSH Key Replacement1Q2025
Our SSH Key for the SFTP Protocol will be replaced on February 8, 2025, as the old key will expire. The new key will be available for download on our H2H SSH Support after February 3.
FTPS SSL Certificate Replacement
1Q2025
Our SSL certificate for the FTPS protocol will be replaced in February 8, 2025, as the old certificate is expiring. The new certificate will be available for download on our H2H SSL Support page after February 3. Please note that DigiCert will be the new Certificate Authority issuing these certificates (previously Entrust).
SSL AS2, HTTPS, NDM Certificate Replacement2Q2025
Our SSL certificate for the AS2, HTTPS, NDM protocols will be replaced in 2Q2025, as the old certificates will expire. The new certificates will be available for download on our H2H SSL Support. Please note that DigiCert will be the new Certificate Authority issuing these certificates (previously Entrust).
Transport Authentication Key requirement update 2Q2025
Beginning in 2Q2025, all transport authentication keys and certificates must have a finite validity period of 1 year or less. For SSH keys, we will install renewal keys for a 1 year usage period.
