Symmetric Proxy Re-encryption CLI

Implementation of proxy re-encryption scheme for symmetric key cryptography defined in 10.1109/IWBIS.2017.8275110

Example usage

To see the available commands and options, run: ./proxy_reencryption -help

To create new key use openssl rand -out <FILE> 48

Encryption

./proxy_reencryption encrypt \
  --keys-path "./example/keys.key" \
  --counter 10 \
  --plaintext-path "./example/plaintext" \
  --iv-output-path "./example/iv" \
  --ciphertext-output-path "./example/ciphertext"

Generate Re-encryption Key

./proxy_reencryption generate-key \
  --keys-path "./example/keys.key" \
  --plaintext-path "./example/plaintext" \
  --reencryption-keys-output-path "./example/reencrypt_keys.key" \
  --decryption-keys-output-path "./example/decrypt_keys.key"

Re-encryption

./proxy_reencryption reencrypt \
  --keys-path "./example/reencrypt_keys.key" \
  --ciphertext-input-path "./example/ciphertext" \
  --iv-input-path "./example/iv" \
  --reencrypted-output-path "./example/reencrypted"

Decryption

./proxy_reencryption decrypt \
  --keys-path "./example/decrypt_keys.key" \
  --counter 10 \
  --iv-input-path "./example/iv" \
  --ciphertext-input-path "./example/reencrypted" \
  --plaintext-output-path "./example/new_plaintext"
