Generate EC (ECDSA/ECDH) Keypair

eckles [format] [curve|encoding]

Generate ECDSA JWK

eckles [jwk] [P-256|P-384]

# Default P-256 (prime256v1, secp256r1)
eckles jwk

# Use P-384 (secp384r1)
eckles jwk P-384

Generate ECDSA PEM

eckles [sec1|pkcs8|ssh] [P-256|P-384]

eckles sec1

eckles pkcs8 P-256

eckles ssh P-384

Generate ECDSA DER

eckles [sec1|pkcs8] [der]

eckles sec1 der > privkey.ec.sec1.der 2> pub.ec.spki.der

eckles pkcs8 der > privkey.ec.pkcs8.der 2> pub.ec.spki.der

Convert ECDSA PEM to JWK

eckles [pemfile] [public]

eckles privkey.pem > privkey.jwk.json

eckles pub.pem > pub.jwk.json

eckles privkey.pem public > pub.jwk.json

eckles id_rsa > privkey.jwk.json

eckles id_rsa public > pub.jwk.json

eckles id_rsa.pub > pub.jwk.json

Convert ECDSA JWK to PEM

eckles [jwk-keyfile] [format]

eckles privkey.jwk.json sec1 > privkey.pem

eckles privkey.jwk.json pkcs8 > privkey.pem

eckles privkey.jwk.json spki > pub.pem

eckles privkey.jwk.json ssh > id_rsa.pub

eckles pub.jwk.json spki > id_rsa.pub

eckles pub.jwk.json ssh > id_rsa.pub

Convert ECDSA PEM to SSH

This is a two-step process, at the moment.

Only public keys are necessary, but private keys may be used.

eckles privkey.pem > privkey.jwk.json

eckles privkey.jwk.json pkcs8 > id_rsa

eckles privkey.jwk.json ssh > id_rsa.pub

eckles pub.pem > pub.jwk.json

eckles pub.jwk.json ssh > id_rsa.pub

Convert ECDSA SSH to PEM

This is a two-step process, at the moment.

Only public keys are necessary, but private keys may be used.

eckles id_rsa > privkey.jwk.json

eckles privkey.jwk.json sec1 > privkey.pem

eckles privkey.jwk.json pkcs8 > privkey.pem

eckles id_rsa.pub > pub.jwk.json

eckles privkey.jwk.json spki > pub.pem
