Экспорт и импорт сертификата PKCS#12

openssl pkcs12 -export -out mycert.pfx -in mycert.pem -inkey mykey.pem -name "My Certificate"

Надо будет ввести любой пароль (придумать).

Должен быть вывод типа этого: 

# openssl pkcs12 -export -out mycert.pfx -in mycert.pem -inkey mykey.pem -name "My Certificate"
Enter Export Password:
Verifying - Enter Export Password:

У вас должен появится файл mycert.pfx.

Чтобы импортировать сертификат PKCS#12 сделаем следующее: 

openssl pkcs12 -in mycert.pfx -out mycert1.pem

надо будет ввести пароль, созданный при экспроте.

Примерный вывод будет таким: 

# openssl pkcs12 -in mycert.pfx -out mycert1.pem
Enter Import Password:
MAC verified OK
Enter PEM pass phrase:

hhh5

openssl ciphers -v

Должен быть вывод типа этого:

hhh6

openssl ciphers -v

Должен быть вывод типа этого:

hhh7

openssl ciphers -v

Должен быть вывод типа этого:

hhh8

openssl ciphers -v

Должен быть вывод типа этого:

hhh9

openssl ciphers -v

Должен быть вывод типа этого:

hhh10

openssl ciphers -v

Должен быть вывод типа этого:
