keytool 有没有办法打印证书的公钥？我试过了:
keytool -printcert -file client.crt
但它只提供以下信息:
Owner: CN=client, OU=as, O=as, L=as, ST=as, C=as
Issuer: EMAILADDRESS=as, CN=ca, OU=as, O=as, L=as, ST=as, C=as
Serial number: 3
Valid from: Tue Apr 10 12:18:47 GMT+05:30 2012 until: Wed Apr 10 12:18:47 GMT+05
:30 2013
Certificate fingerprints:
MD5: 26:C0:29:E9:8C:AB:C3:9E:95:38:74:8A:87:D3:86:8D
SHA1: 5C:5A:BA:47:44:83:7E:CB:48:BE:DD:E5:39:51:24:42:C6:C5:60:8B
SHA256: DA:26:B8:C8:F4:04:3E:62:F3:7F:3B:EC:1D:9F:85:66:28:00:45:55:66:
15:FF:BB:37:77:97:59:F0:EC:0B:B6
Signature algorithm name: SHA1withRSA
Version: 1
这里面没有公钥。
最佳答案
你可以这样做:
keytool -list -rfc -keystore mykeystore.jks -alias certificate_alias -storepass password
示例运行:
PS c:\sample> keytool -list -rfc -keystore mykeystore.jks -alias cert_alias -storepass password
Alias name: cert_alias
Creation date: Apr 25, 2014
Entry type: PrivateKeyEntry
Certificate chain length: 1
Certificate[1]:
