Convert an old style .p12 to .pem (unsupported algorithm RC2-40-CBC)
openssl has a key algorithm provider called legacy. Just try with: openssl pkcs12 -in mycert.p12 -legacy -nodes
pkcs#12
cURL OpenSSL error error:0308010C:digital envelope routines::unsupported
Meta: this isn’t really programming or development, and would probably be better on superuser or maybe security.SX, but this is issue is likely to become more common as OpenSSL 3.0 spreads and I wanted to get the answer out. OpenSSL 3.0.x (and up) by default doesn’t support old/insecure algorithms, but until recently most software that … Read more
How to create a certificate into a PKCS12 keystore with keytool?
If the keystore is PKCS12 type (.pfx) you have to specify it with -storetype PKCS12 (line breaks added for readability): keytool -genkey -alias <desired certificate alias> -keystore <path to keystore.pfx> -storetype PKCS12 -keyalg RSA -storepass <password> -validity 730 -keysize 2048
What are the merits of JKS vs PKCS12 for code signing?
If you’re working in Java then the Java Key Store is a fairly natural place to store private keys.Java applications typically expect to get the keys they need from JKS, and it’s easy to access from your own Java apps. JKS is not accessible (without jumping through a few hoops) from outside Java, though. PKCS#12 … Read more
Need help converting P12 certificate into JKS
If you do have Keytool application and your PKCS#12 file, launch the one-line command: keytool -importkeystore -srckeystore [MY_FILE.p12] -srcstoretype pkcs12 -srcalias [ALIAS_SRC] -destkeystore [MY_KEYSTORE.jks] -deststoretype jks -deststorepass [PASSWORD_JKS] -destalias [ALIAS_DEST] You’ll need to modify these parameters: MY_FILE.p12: indicate the path to the PKCS#12 file (.p12 or .pfx extension) to be converted. MY_KEYSTORE.jks: path to the … Read more
What is the difference between a PKCS12 keystore and a PKCS11 keystore?
PKCS#12 is a file format (often called .p12 or .pfx) where you can store a private key and certificates. It’s used for converting/transporting keys and certificates, mainly. If you export a private key + certificate from your browser, it’s likely going to be in that format. PKCS#11 is an interface, usually used to talk to … Read more
How to extract private key from pfx file using openssl? [closed]
Your command is correct, and gives you the encrypted private key in PKCS#8 format. If you need the unencrypted private key, just add the -nodes option: openssl pkcs12 -in filename.pfx -nocerts -nodes -out key.pem If you need the private key in old RSA format, you should convert the given key with the openssl pkcs8 command: … Read more
How can constructing an X509Certificate2 from a PKCS#12 byte array throw CryptographicException(“The system cannot find the file specified.”)?
Do you have PKCS#12 or just PFX-file? In the Microsoft world it is the same, but other think another (see this archived page). You can try just following X509Certificate2 cert = X509Certificate2(byte[] rawData, “password”); X509Certificate2 cert2 = X509Certificate2(byte[] rawData, “password”, X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.Exportable); (X509Certificate2(Byte[])) or X509Certificate2 cert = X509Certificate2(“C:\Path\my.pfx”, “password”); (see X509Certificate2(String, String) … Read more
What causes keytool error “Failed to decrypt safe contents entry”?
Sometimes this error is symptomatic of using an incorrect password for the p12 key.
Enter PEM pass phrase when converting PKCS#12 certificate into PEM
“Enter PEM pass phrase” because openssl doesn’t want to output private key in clear text. The password is used to output encrypted private key Below command can be used to output private key in clear text. No password is then asked. openssl pkcs12 -nodes -in me.p12 -out me.pem
