2023-02-13 Buffer size of signatures

13. February 2023, worldwide

We experienced that the buffer sizes (binary) of 30,000 bytes for signatures and 15,000 bytes for timestamps recommended for the CA4 changeover were not always adhered to in the signature applications and led to problems when extending the key size of the OCSP certificate for LTV signatures. Therefore, we ask all signature applications to check the buffer sizes for signatures again in case of problems. See also Swisscom CA 4 · SwisscomTrustServices/AIS Wiki · GitHub
