OpenSSL Question, Elliptic Curve Cryptography (ECC) TLS

2014-04-01 Thread Landen Landens
How do I verify the modulus of an openssl Elliptic Curve Cryptography (ECC) private key? If this were RSA, I would run: openssl x509 -noout -modulus -in certificateFileName.crt | openssl md5 openssl rsa -noout -modulus -in privateKeyFileName.key | openssl md5 openssl req -noout -modulus -in

Well I'm fumbling my way through this right now myself. Nils is the expert (he wrote it). but look in the crypto/ecdsh directory and look at the test programs. They might help. Frank "Henrik N. Rask" wrote: > I am trying to figure out exactly how much support for elliptic cu

I am trying to figure out exactly how much support for elliptic curve cryptography exists in the 0.9.8 snapshots (the lack of documentation is making this a bit difficult). Specifically i was wondering if there exists functions for simple public/private encryption/decryption similar to

[Q] Free package that implements Elliptic Curve Cryptography

1999-08-04 Thread Kwon JaeHwan
Sorry to ask the question that is unrelated to openssl. Is there any free and open source that implements ECC (Elliptic Curve Cryptography) ? Of course, it must implement ECDH key exchange, handle ECDSA based certificates, and handle ECDSA signing
