Generate Elliptic Key Pair Github

Nov 19, 2018 How can I generate a public key with specific domain parameters (a, b, p, x, y, n, h) according to secp256r1. GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. You could create a key pair outside of the sdk and import the public key to the sdk.
Edit on GitHub; opensshkeypair – Generate OpenSSH private and public keys. For ECDSA keys, size determines the key length by selecting from one of three elliptic curve sizes: 256, 384 or 521 bits. Attempting to use bit lengths other than these three values for ECDSA keys will cause this module to fail. The algorithm used to generate.

Generate self-signed certs with different key types

openssl-notes.txt

*** RSA

# Generate self-signed certificate with RSA 4096 key-pair

openssl req -x509 -nodes -days 3650 -newkey rsa:4096 -keyout rsakey.pem -out rsacert.pem

# print private and public key

openssl rsa -in rsakey.pem -text -noout

# print certificate

openssl x509 -in rsacert.pem -text -noout

# generate PKCS#12 container

openssl pkcs12 -export -inkey rsakey.pem -in rsacert.pem -out rsacred.p12

*** ECDSA

# Generate self-signed certificate with ECDSA using two common curves

openssl req -x509 -nodes -days 3650 -newkey ec:<(openssl ecparam -name prime256v1) -keyout ecdsakey.pem -out ecdsacert.pem

openssl req -x509 -nodes -days 3650 -newkey ec:<(openssl ecparam -name secp384r1) -keyout ecdsakey.pem -out ecdsacert.pem

# print private and public key + curve name

openssl ec -in ecdsakey.pem -text -noout

# print certificate

openssl x509 -in ecdsacert.pem -text -noout

# generate container

openssl pkcs12 -export -inkey ecdsakey.pem -in ecdsacert.pem -out ecdsacred.p12

Which curve to choose?

'Interoperability' means that you would probably prefer it if SSL clients can actually

connect to your server; otherwise, having a SSL server would be rather pointless.

This simplifies the question a lot: in practice, average clients only support two curves,

the ones which are designated in so-called NSA Suite B: these are NIST curves P-256 and

P-384 (in OpenSSL, they are designated as, respectively, 'prime256v1' and 'secp384r1').

If you use any other curve, then some widespread Web browsers (e.g. Internet Explorer,

Firefox..) will be unable to talk to your server.

*** DSA

# generate both key and DSA parameters (both will be stored in dsakey.pem)

openssl dsaparam -genkey 1024 -out dsakey.pem

openssl req -x509 -new -days 3650 -key dsakey.pem -out dsacert.pem

# print private and public key with DSA params

openssl dsa -in dsakey.pem -text -noout

# print certificate

openssl x509 -in dsacert.pem -text -noout

# print only DSA params from key file

openssl dsaparam -in dsakey.pem -text -noout

# generate container

openssl pkcs12 -export -inkey dsakey.pem -in dsacert.pem -out dsacred.p12

*** Test TLS connection

openssl s_server -accept 1443 -www -key key.pem -cert cert.pem

openssl s_client -showcerts -connect localhost:1443 -CAfile cert.pem
