WebDec 30, 2024 · Use your exported key value from the BLOB as the Hex Key Value in the openssl enc command below. openssl enc -d -rc4-40 -in testFile-NO_SALT-enc.txt -out testFile-NO_SALT-dec.txt -K "Hex Key Value" -nosalt -nopad. This will decrypt the file that was encrypted on the Windows machine using CryptEncrypt. WebIn CBC mode, you encrypt a block of data by taking the current plaintext block and exclusive-oring that wth the previous ciphertext block (or IV), and then sending the result of that through the block cipher; the output of the block cipher is the ciphertext block. GCM mode provides both privacy (encryption) and integrity.
