+# RsaCtfTool
+
+> RSA attack tool for CTF challenges - recover private keys from weak public keys and/or decrypt data.
+> More information: <https://github.com/RsaCtfTool/RsaCtfTool>.
+
+- Recover a private key from a public key file:
+
+`RsaCtfTool.py --publickey {{path/to/key.pub}} --private`
+
+- Decrypt a file using a public key:
+
+`RsaCtfTool.py --publickey {{path/to/key.pub}} --decryptfile {{path/to/ciphered_file}}`
+
+- Decrypt a specific ciphertext string:
+
+`RsaCtfTool.py --publickey {{path/to/key.pub}} --decrypt "{{ciphertext}}"`
+
+- Dump RSA key components (e.g., modulus, exponent) from a key file:
+
+`RsaCtfTool.py --dumpkey --key {{path/to/key.pub}}`
+
+- Run a specific attack (e.g., Fermat factorization) to recover the private key:
+
+`RsaCtfTool.py --publickey {{path/to/key.pub}} --private --attack fermat`
+
+- Generate a public key from modulus (n) and exponent (e):
+
+`RsaCtfTool.py --createpub -n {{modulus}} -e {{exponent}}`
+
+- Attempt all available attacks to recover the private key:
+
+`RsaCtfTool.py --publickey {{path/to/key.pub}} --private --attack all`
