Thank you immediately answer. PKCS8, PEM, and RFC4716 formats were created and tested with the ssh-keygen command. PKCS8 and PEM formatting was successful. RFC4716 is the default on Windows10, and PEM is the default on CentOS7. Does OpenSSL have any plans to support RFC4716 format in the futu

Hello, most probably the key is stored in the OpenSSH private key format. You'll need to use ssh-keygen -p -m PKCS8 to convert the key into a format that OpenSSL can read. Tomas Mraz, OpenSSL On Wed, 2022-10-05 at 15:00 +0900, Imazu Setsuo wrote: > Hello. > > When I read the RSA private key file

I'll give it a try. The Certification Authority (CA) that released the certificate has an RSA key. That was used to generate the signature in the cert, that tells users that the CA verified the Certificate Subject identity and that they hold the secret key associated with the Subject's Public Key.

Oh, forgot one other issue: I also need to pick apart the RSA keys into their constituent exponents, modulus, etc. as BN's that I can then compare to bit-strings. With the old RSA_* routines this was trivial. How does one do this with the EVP_PKEY_* interface so that it works with 1.1.x and 3.

Solved. Thanks, Mounir. Changing my PEM_read_bio_RSA_PublicKey() to PEM_read_bio_RSA_PUBKEY() did the trick. I don't understand why there are two of these, but I'm new to OpenSSL, so I won't complain about that which I don't sufficiently understand. Dave On Fri, Feb 18, 2011 at 10:15 AM, David He

Re: RSA public/private keys only work when created programatically.

Thanks for the response, but adding the -pubout switch did not change anything. Actually, I had already been using it, but forgot to type it in my email. Just to make sure though, I recreated the keys and tried again with: > openssl genrsa -out rsaprivatekey.pem 2048 > openssl rsa -in rsaprivateke

Re: RSA public/private keys only work when created programatically.

Hi, Your command line that create the public key is missing the -pubout switch that tells the rsa utility to output a public key. So, this command should look like : openssl rsa -in rsaprivatekey.pem -out rsapublickey.pem -pubout . Without it, it will just output the private key as is. More

Alex, We use OpenSSL on Sun Solaris SPARC architecture, which is big endian. Never had a problem. No clue about how to compile/link on your ARM cpu though. Dan Please respond to openssl-users@openssl.org Sent by:owner-openssl-us...@openssl.org To: cc: (bcc: Dan Mitton/YD/R

Re: RSA OAEP encrypt with a label

Thank you Martin. I have tried using the function, however using the code I have pasted below I get the error "Error = oaep decoding error" when trying to unpadd to retrieve the original data. For simplicity the code I have added here does not encrypt/decrypt, but only attempts to pad and unpadd.
