One of my friends was hacked, all of his disk was encrypted.
The hackers are requesting money, that obviously we don’t want to pay.
I am wondering if it’s possible to decrypt everything, given that I have some original backed up files (pla… Continue reading Decrypting files given a sample encrypted file and original
I am trying to decrypt a given TLS record layer sent by a client using OpenSSL. The TLS version is TLS 1.2 and the cipher suite is TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA.
The encrypted record layer is given by 16030300400325f41d3ebaf8986da712c… Continue reading Decrypt TLS record layer using OpenSSL
