Web2 de abr. de 2024 · I was now informed that the file has been encrypted with Openssl with a salted password. To simplify the brute force process, I had to find the algorithm used during the encryption phase. The command openssl enc -ciphers will display a list of all the algorithms supported by Openssl, it helped me to define a first list of ciphers. WebOpenSSL uses a salted key derivation algorithm. The salt is a piece of random bytes generated when encrypting, stored in the file header; upon decryption, the salt is retrieved from the header, and the key and IV are re-computed from the provided password and salt. daily hunts news

Web8 de dez. de 2024 · Hashing is used to created a fixed length encryption key from the user-supplied passphrase. The purpose of the salt is to avoid creating the same key from the same passphrase, to protect against rainbow table attacks. The passphrase and salt are concatenated, then hashed. The initialization vector has a different purpose. Webbase64-decode the output from openssl, and utf-8 decode the password, so that we have the underlying bytes for both of these. The salt is bytes 8-15 of the base64-decoded openssl output. Derive a 48-byte key using pbkdf2 given the password bytes and salt with 10,000 iterations of sha256 hashing.
