retrive the private key from RSA KEON CA certificate

[Wu Junwei]

Hi, all,   Maybe my question in last time was not clear, so I ask again by another description.   I have a CA certificate exported from RSA KEON, which is PEM encoded pkcs#12 certificate (listed below.) It seems encoded by base64 , I have tried different methods to try to get the private key inside the certificate by the functions in the openssl.  ( such as using FORMAT_PKCS12 and FORMAT_PEM in apps.c/load_key().) But it always failed. It is exported by me so I know password used for the private key protection.   Question: 1,So, is it possible to retrive the private key inside the pkcs#12 certificate as follows exported from KEON? 2,If it is possible , how can I retrieve the private key in it by the functions in OpenSSL?   Thanks in advance.   /******************************** the certificate exported from KEON *****************************/ The following passphrase protected PKCS #12 object, displayed in PEM encoded format, contains the certificate and private key for CATest1_1. It also contains the friendly name "CATest1_1". -----BEGIN CERTIFICATE AND KEY----- MIIF0wIBAzCCBY0GCSqGSIb3DQEHAaCCBX4EggV6MIIFdjCCBXIGCSqGSIb3DQEH AaCCBWMEggVfMIIFWzCCAvAGCyqGSIb3DQEMCgECoIICpTCCAqEwGwYKKoZIhvcN AQwBAzANBAhGyCbImOLSZwIBAQSCAoDPZJurj3+1kM7e4/cPp1kYM1qcsLPAQsIQ 5eycmvECjgi7ZILdv28dvm3RNjTlmrH/Zr29i2gHANSgxRW8VQ5KFq/BZIEOG+KN EsyVC/Xwpp1joEvxODb2UIymruFxqTAJYJIbXtnH4SHUzp2WXupmt8Cme8axoTwW 1Dms4u/G/VyP9qlCVQOFfBpEdBzy+U9DC2QTnaN4XA6Sx8BxMS8TGTP+3LTPDK4b k3ROX80znDIqd3povWsPk1MGCi1s6l6c817Nm2k8eu9S7agGsKmtYw/VzdbRIGYM oP6l8H6IL9dvWBeMW8WgZj9rWFDg89CZW9qX3LuJ6IDqSJ8MU9xvs1ZdJHbjtABh nzoZoSoPuMEYHf6L2JctLIEHNUJNYefh+Ck+INsNlofWW7OnavgT9Omrb4TiW1IA mGe4F6gK6benv1bDTltTDPabraLE3jJY4VE4CtlsZeFLwZ6Y5q2JnSbSJCxZtMBP zp6OOIkS8ZJK1BCZBQCIIw+1NLTRzrrfnJQuEcJ41LZhfCw2xdwVM4qtc7I3SXQA Xs/UYFlvif4dMWyG5PtuQ/PrzM4OJ5KVXzjYRqa8ixLvDtqYsqwzlzGezz1HnKvE vNTbT9qajK8AIxwnhhQ4ErMDVTbtjYrvWNfseu8WwRTIZfy3YLJS1vbwHNmdukql AbsXmYGDEjgEgOuzS0I0qH3m/CoH1g6QEOxAFqXBU9HuZ91I+s7gprJwi5/dziMv rl9WRkcDnTltijijvpXnTIGylWpS9To4pQhEuxa5GsNyvUgmQtU5v11hZWF+V3a4 G3ZMDksr34VzflfHsIjfx6to3NUWVP1xo6Q+LjNKfie2ceM1fESUMTgwEwYJKoZI hvcNAQkVMQYEBAAAAAEwIQYJKoZIhvcNAQkUMRQeEgBDAEEAVABlAHMAdAAxAF8A MTCCAmMGCyqGSIb3DQEMCgEDoIICGDCCAhQGCiqGSIb3DQEJFgGgggIEBIICADCC AfwwggFlAhB5U/4UwzOflq9K1i22Xqv3MA0GCSqGSIb3DQEBBQUAMD0xCzAJBgNV BAYTAkpQMRIwEAYDVQQKEwlGdWppeGVyb3gxDDAKBgNVBAsTA0NTVzEMMAoGA1UE AxMDV3UxMB4XDTAzMDYxOTA2MDAxMVoXDTA2MDQyNjExMDAxMVowQTELMAkGA1UE BhMCSlAxCzAJBgNVBAoTAmZ4MQwwCgYDVQQLEwNjc3cxFzAVBgNVBAMTDnNvbiBv ZiBDQVRlc3QxMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDegClxP28gBnrJ s5RVqY5TMM5AIoHHDmQeIvj55DtMmIuRHnk6kBPmZJtqNetPwRfRwMIBtu9/T1Vy psOO4QuAZz1C5wvRbC4Ylh4/nAnR1xY4fIN5lTflam1ohVUFZmx9jRNxp89VznSp 56wcsiJMzNrB6Nev3j4bfKlz7iULCQIDAQABMA0GCSqGSIb3DQEBBQUAA4GBAF2l QSp+wQ7n98p7VeBh9wVnv/TTzb9ebgDEZSb9I6FZpeQ3242/cTsoe2y2NtmhjmmY OURbW66jhV/pKZliEFM53Fc7xoPstN0SKFQyOHUsO0lQbZu+o8wk6oWptg/KPEZR 1Xx6zu3E2Qwx+6vqOFGrfDdiQe7pDp4a4j6oYP1GMTgwEwYJKoZIhvcNAQkVMQYE BAAAAAEwIQYJKoZIhvcNAQkUMRQeEgBDAEEAVABlAHMAdAAxAF8AMTA9MCEwCQYF Kw4DAhoFAAQUy0Edy1Bxr38oc0jumiqofA19OeYEFIjlSSn4K2WLg6m2D9YYQgx6 +bjkAgIEAA== -----END CERTIFICATE AND KEY-----   wjw
