| Bugfix | |
| * In PEM writing functions, fill the trailing part of the buffer with null | |
| bytes. This guarantees that the corresponding parsing function can read | |
| the buffer back, which was the case for mbedtls_x509write_{crt,csr}_pem | |
| until this property was inadvertently broken in Mbed TLS 2.19.0. | |
| Fixes #3682. |
