RSA Stuff

TODO

• Implement rsa-encrypt, rsa-decrypt, rsa-sign & rsa-verify
• Modify rsa-keygen to to export the keypair in PEM format

Building

Make sure clang, lld, compiler-rt & make is installed

Then build the programs by running:

make -j$(nproc)

Usage

Generate a key:

./bin/rsa-keygen

Encrypt a message:

./bin/rsa-encrypt <message> <public key>

For example:

./bin/rsa-encrypt "message.txt" "data/pubkey.asc"

Decrypt a message:

./bin/rsa-decrypt <message> <private key>

For example:

./bin/rsa-decrypt "message.txt.enc" "data/privkey.asc"

Sign a message:

./bin/rsa-sign <message> <private key>

For example:

./bin/rsa-sign "message.txt" "data/privkey.asc"

Verify a message:

./bin/rsa-verify <message> <public key>

For example:

./bin/rsa-verify "message.txt.asc" "data/pubkey.asc"
