Cryptography Tutorials - Herong's Tutorial Examples

∟Migrating Keys from "OpenSSL" Key Files to "keystore"

∟"keytool -importkeystore" Importing PKCS#12 Files

This section provides a tutorial example on how to import a private key stored in a PKCS#12 file into a JKS (Java KeyStore) file with the 'keytool -importkeystore' command.

Since Java uses JKS (Java KeyStore) as the keystore file type, I want to try to convert my PKCS#12 file, openssl_key_crt.p12, to a JKS file with the "keystore -importkeystore" command: 

herong> keytool -importkeystore -srckeystore openssl_key_crt.p12 \
   -srcstoretype pkcs12 -srcstorepass p12pass -srcalias openssl_key_crt \ 
   -destkeystore openssl_key_crt.jks -deststoretype jks \
   -deststorepass jkspass

herong> keytool -list -keystore openssl_key_crt.jks -storetype jks \
   -storepass jkspass

Keystore type: JKS
Keystore provider: SUN

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...

There was no trouble at all. "keytool -importkeystore" command has a lots of options. But they are very easy to understand.
