Libraries
Library rsa
To use this library in your code:
import crypto.rsaSupport for RSA (Rivest–Shamir–Adleman) public-key cryptography.
RSA can be used for both encryption, and digital signatures.
Examples
Signing and Verifying
import crypto.rsa
// Assuming 'private-key' and 'public-key' are available as rsa.RsaKey.
message := "Hello world"
key := rsa.RsaKey.generate --bits=2048
signature := key.sign message
if key.verify message signature:
print "Signature is valid"
else:
print "Signature is invalid"
Alternative hashing
If you need to use other hash algorithms (e.g. SHA-1):
signature := private-key.sign message --hash=rsa.RsaKey.SHA-1
