I used to access "Trusted credentials" by: KeyStore keystore = KeyStore.getInstance("AndroidCAStore"); through the above code I can then access system & user trusted credentials. But now, in Android 7, user installed certificate goes to a separate place called "User credentials" under Settings --> Security --> User credentials . My

How to load a PKCS#12 file in OpenSSL programmatically?

阅读更多关于 How to load a PKCS#12 file in OpenSSL programmatically?

In an SSL Server Application based on OpenSSL, how can we load a PKCS#12 file programmatically? Also, can I load a PKCS#12 file having Certificate, Key & CAs in the same file in OpenSSL? Mathias Brossard Yes you can load a PKCS#12 file containing certificate, key and CAs in the same file with OpenSSL. Use d2i_PKCS12_fp() or d2i_PKCS12_bio() to load the PKCS#12 file. Optionally use PKCS12_verify_mac() to verify the password. Use PKCS12_parse() which decrypts and extracts key, certificate and CA chain for you.
