我使用这个脚本生成了3个密钥/证书:
#!/bin/sh
AUTH='/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com'
if [ "$1" == "" ]; then
echo "Create a test certificate key."
echo "Usage: $0 NAME"
echo "Will generate NAME.pk8 and NAME.x509.pem"
echo " $AUTH"
exit
fi
openssl genrsa -3 -out $1.pem 2048
openssl req -new -x509 -key $1.pem -out $1.x509.pem -days 10000 \
-subj "$AUTH"
echo "Please enter the password for this key:"
openssl pkcs8 -in $1.pem -topk8 -outform DER -out $1.pk8 -passout stdin
输出结果为:
releasekey.pem
releasekey.pk8
releasekey.x509.pem
然后我尝试使用此命令解密它:
openssl pkcs8 -in ~/.android-certs/releasekey.pk8 -inform DER
所以,输出是
alex-garmas-osx:android alex-garmash$ openssl pkcs8 -in ~/.android-
certs/releasekey.pk8 -inform DER
Enter Password:
-----BEGIN PRIVATE KEY-----
CONTENT OF PRIVATE KEY HERE
-----END PRIVATE KEY-----
它运作正常。 releasekey.pk8
没有密码短语
当我对命令执行相同操作时:
openssl pkcs8 -in ~/.android-certs/releasekey.pk8 -inform DER -nocrypt
我有一个错误:
140735885419528:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag:tasn_dec.c:1200:

在documentation我看到我可以使用选项-nocrypt
,但为什么会失败?
非常感谢 @bartonjs 的解释。要解决此问题,您需要将 -nocrypt 标志添加到脚本的最后一个命令,然后您可以使用上面的命令来解密生成的密钥
#!/bin/sh
AUTH='/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com'
if [ "$1" == "" ]; then
echo "Create a test certificate key."
echo "Usage: $0 NAME"
echo "Will generate NAME.pk8 and NAME.x509.pem"
echo " $AUTH"
exit
fi
openssl genrsa -3 -out $1.pem 2048
openssl req -new -x509 -key $1.pem -out $1.x509.pem -days 10000 \
-subj "$AUTH"
echo "Please enter the password for this key:"
openssl pkcs8 -in $1.pem -topk8 -outform DER -out $1.pk8 -passout stdin -nocrypt
答案 0 :(得分:2)
系统会提示您输入空密码,但成功,-nocrypt
失败。
"用空密码加密""和#34;未加密" (虽然对于一个粗暴的人来说,并不是一个人)。
未加密的PKCS#8 blob看起来像(ASN.1):
PrivateKeyInfo ::= SEQUENCE {
version Version,
privateKeyAlgorithm PrivateKeyAlgorithmIdentifier,
privateKey PrivateKey,
attributes [0] IMPLICIT Attributes OPTIONAL }
如果已加密,那么
EncryptedPrivateKeyInfo ::= SEQUENCE {
encryptionAlgorithm EncryptionAlgorithmIdentifier,
encryptedData EncryptedData }
EncryptionAlgorithmIdentifier ::= AlgorithmIdentifier
EncryptedData ::= OCTET STRING
所以-nocrypt
告诉OpenSSL它应该直接期望第一个结构,而你的看起来像第二个(特别是,SEQUENCE的第一个孩子不是INTEGER,而是另一个SEQUENCE)。 / p>
并说你的数据是用空密码加密的,并不代表它是用某种空密钥加密的。 PKCS#8文件的创建者几乎肯定经历了为PBKDF2算法选择随机盐的麻烦,然后将其与空密码结合以产生输出。那些数据仍然是噪音,只是......比正常情况更容易发出强力噪音。
