"keytool -list" Verifying PKCS#12 Files
This section provides a tutorial example on how to merge a private key and its self-signed certificate into a single PKCS#12 file, with can be then encoded as PEM and encrypted with DES.
Since Java SE "keytool" command support PKCS#12 files,
I want to try it with my PKCS#12 file, openssl_key_crt.p12, created by "OpenSSL"
with the following tests:
- Use "keytool -list" command to display what's in the PKCS#12 file.
- "keytool -exportcert" command only exports the self-signed certificate from a PrivateKeyEntry in a keystore.
My command session was recorded as blow:
C:\herong>keytool -list -keystore openssl_key_crt.p12 -storetype pkcs12 \
Keystore type: PKCS12
Keystore provider: SunJSSE
Your keystore contains 1 entry
openssl_key_crt, Jul 29, 2007, PrivateKeyEntry,
Certificate fingerprint (MD5): 1D:D4:AC:96:53:25:9F:1A:D0:A7:46:6C...
C:\herong>keytool -exportcert -keystore openssl_key_crt.p12 \
-storetype pkcs12 -storepass p12pass -alias openssl_key_crt \
-file keytool_openssl_crt.pem -rfc
Certificate stored in file <keytool_openssl_crt.pem>
Notes on the commands and options I used:
- "keytool -list" command lists what's in the keystore file.
- "-keystore openssl_key_crt.p12" option specifies the keystore file, a PKCS#12 file generated by "OpenSSL".
- "-storetype pkcs12" option specifies the type of the keystore file, "jks" or "pkcs12".
- "-storepass p12pass" option specifies the password to open the keystore file.
- "keytool -exportcert" command exports the self-signed certificate out of the keystore file.
- "-rfc" option tells keytool to write the certificate file with PEM (RFC1421) encoding.
The tests were successful and helped me to learn that:
- The PKCS#12 file generated by "OpenSSL" does meet the PKCS#12 standard.
- "OpenSSL" and "keytool" can share keystore files in PKCS#12 format.
As an exercise, you can open "openssl_crt.pem" and "keytool_openssl_crt.pem".
They should contain the same Base64 encoded strings.
In the next section, I want to try to convert the PKCS#12 file to a JKS (Java KeyStore) file.
