RSA private key

[filipgrzelak]

i want to sign a data with KJUR library.

I have got RSA PRIVATE KEY which looks like that.

const PRIVATE_KEY = "\---- BEGIN RSA PRIVATE KEY---- ... ----END RSA PRIVATE KEY----
and i want to sign data like this

const keyPEM = KEYUTIL.getKey(PRIVATE_KEY)

and when i want compile this code this error occurs: "Error: unsupported PKCS#1/5 hexadecimal key"

What should i do to resolve this problem. I have to use KJUR library. Thanks for help

I try a lot of combinations of examples and i dont have more ideas

Can you send me your key? Then I can do investigation.

[filipgrzelak]

this is my key

[filipgrzelak]

and it is generated with commands you sent me below. the error is the same

[filipgrzelak]

when i remove \n at the end of each line the error still occurs

[kjur]

Otherwise, can you use another private key created by following commands:

# generating RSA 2048bit PKCS#8 format private key having "-----BEGIN PRIVATE KEY-----"
% openssl genrsa 2048 > a.prv.p8
# convert it from PKCS#8 to PKCS#1/#5 format like yours having "----BEGIN RSA PRIVATE KEY-----" 
% openssl rsa -in a.prv.p8 -out a.prv.p5 -traditional

Then could you confirm the keys "a.prv.p8" and "a.prv.p5" works?

[filipgrzelak]

ok, finally after a few tries it start works. Thanks
