1、How do I generate an RSA key?
# default 512-bit key, sent to standard output
openssl genrsa
# 1024-bit key, saved to file named mykey.pem
openssl genrsa -out mykey.pem 1024
# same as above, but encrypted with a passphrase
openssl genrsa -des3 -out mykey.pem 1024
2、How do I generate a public RSA key?
openssl rsa -in mykey.pem -pubout
3、RSA encrypt with public key?
cat plain.txt | openssl rsautl -encrypt -pubin -inkey rsa.pub.pem > cipher.txt
4、RSA decrypt with private key?
cat cipher.txt | openssl rsautl -decrypt -inkey rsa.pri.pem
5、Abstract the common Modulus from the public key?
OpenSSL> rsa -pubin -in public.pem -modulus -noout
OpenSSL> rsa -in private.pem -modulus
6、Abstract the Public Exponent Values?
OpenSSL> rsa -pubin -in public.pem -text -noout
7、Abstract the Private Exponent Values?
OpenSSL> rsa -in private.pem -text -noout
8、Convert pkcs#12 Private Key to pkcs#8 pem?
openssl pkcs8 -topk8 -inform PEM -outform PEM -in private_key.pem -out private_key.pem -nocrypt
或者
pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt
9、Extracting Certificate and Private Key Files from a .pfx File？
1)Run the following command to export the private key: openssl pkcs12 -in certname.pfx -nocerts -out key.pem -nodes
2)Run the following command to export the certificate: openssl pkcs12 -in certname.pfx -nokeys -out cert.pem
3)Run the following command to remove the passphrase from the private key: openssl rsa -in key.pem -out server.key
10、Use openssl decode base64 encoding string?
openssl enc -in cipher.b6 -out cipher.bin -d -a
11、Use openssl to base64 encode/decode?
1)encode：echo "abc" | openssl base64
2)decode：echo "YWJjCg==" | openssl base64 -d
12、Use openssl to md5 encoding?
echo -n "abc" | openssl md5
13、Use openssl to encode AES/DES?
1)echo "abc" | openssl aes-128-cbc -k 123 -base64
2)echo "U2FsdGVkX19sDbym0tiqS4AIvnWeF/tUkCr6x/ZV9bc=" | openssl aes-128-cbc -k 123 -base64 -d
14、convert p12 to apns pem.
openssl pkcs12 -in MyApnsCert.p12 -out MyApnsCert.pem -nodes -clcerts
# default 512-bit key, sent to standard output
openssl genrsa
# 1024-bit key, saved to file named mykey.pem
openssl genrsa -out mykey.pem 1024
# same as above, but encrypted with a passphrase
openssl genrsa -des3 -out mykey.pem 1024
