Openssl

RSA

Generate RSA keys

On Openssl:

• openssl genrsa -out rsa.pem 1024

• openssl rsa -in rsa.pem -pubout -outform pem -out rsa-pub.out

On Coherence:

{ "version": 1 , "algorithm":"RSA", "operation":"gen" , "length": 1024 }

From Openssl to Coherence priv key

• openssl pkcs8 -nocrypt -in rsa.pem -inform PEM -topk8 -outform DER -out rsa.der

• cat rsa.der | xxd -ps | paste -s -d '' > rsa.der.hex

From Openssl to Coherence pub key

• openssl rsa -in rsa.pem -pubout -outform DER -out rsa-pub.der

• cat rsa-pub.der | xxd -ps | paste -s -d '' > rsa-pub.der.hex

From Coherence to Openssl priv key

• cat crsa.der.hex | xxd -r -p - > crsa.der

• openssl rsa -inform der -outform pem -in crsa.der -out crsa.pem

From Coherence to Openssl pub key

• cat crsa-pub.der.hex | xxd -r -p - > crsa-pub.der

• openssl rsa -inform der -outform pem -pubin -in crsa-pub.der -out crsa-pub.pem

DSA

Generate DSA keys

On Openssl:

• openssl dsaparam -out dsa-param.pem 1024

• openssl gendsa -out dsa.pem dsa-param.pem

• openssl dsa -in dsa.pem -pubout -outform PEM -out dsa-pub.pem

On Coherence:

{"operation": "gen", "version": 1, "length": 1024, "algorithm": "DSA"}

From Openssl to Coherence priv key

• openssl pkcs8 -nocrypt -in dsa.pem -inform PEM -topk8 -outform DER -out dsa.der

• cat dsa.der | xxd -ps | paste -s -d '' > dsa.der.hex

From Openssl to Coherence pub key

• openssl dsa -in dsa.pem -pubout -outform DER -out dsa-pub.der

• cat dsa-pub.der | xxd -ps | paste -s -d '' > dsa-pub.der.hex

From Coherence to Openssl priv key

• cat cdsa.der.hex | xxd -r -p - > cdsa.der

• openssl dsa -inform der -outform pem -in cdsa.der -out cdsa.pem

From Coherence to Openssl pub key

• cat cdsa-pub.der.hex | xxd -r -p - > cdsa-pub.der

• openssl dsa -inform der -outform pem -pubin -in cdsa-pub.der -out cdsa-pub.pem
