Algid parse error, not a sequence


java security rsa

I was having this same issue, and the format of the key was NOT the actual problem.
All I had to do to get rid of that exception was to call

java.security.Security.addProvider(         new org.bouncycastle.jce.provider.BouncyCastleProvider());


and everything worked

java security rsa

It means your key is not in PKCS#8 format. The easiest thing to do is to use the openssl pkcs8 -topk8 <...other options...> command to convert the key once. Alternatively you can use the PEMReader class of the Bouncycastle lightweight API.

java security rsa

You must make your PCKS8 file from your private key!

private.pem => name of private key file

openssl genrsa -out private.pem 1024

public_key.pem => name of public key file

openssl rsa -in private.pem -pubout -outform PEM -out public_key.pem

‫‪private_key.pem‬‬ => name of private key with PCKS8 format! you can just read this format in java

openssl pkcs8 -topk8 -inform PEM -in private.pem -out private_key.pem -nocrypt
