2021  As you have access to openssl extension there is a better/safer way of generating iv for the chosen cipher, openssl can also tell you the right length of the iv for the cipher: $iv = openssl_random_pseudo_bytes (openssl_cipher_iv_length ('AES-256-CBC')); It will be in binary format so if you need it in hex use bin2hex ($iv).

It is all about how OpenSSL does its formating and key generation. The ciphertext was actually changing, but the first part of it was staying the same. Let’s encrypt… I have been fuzzing OpenSSL's implementation of several AEAD ciphers in OpenSSL 1.1.1a. For chacha20-poly1305, OpenSSL supports an IV, where IV >= 1 byte and IV <= 16 bytes (CHACHA_CTR_SIZE), with the default IV being 12 bytes or 96-bits Openssl encryption.

I know MYPASSWORD. I could decrypt and then re-encrypt with new known key+IV with: openssl enc -d -aes-256-cbc -pass pass:MYPASSWORD openssl enc -aes-256-cbc -K MYKEY -IV MYIV It ususaly works fine, but sometimes (1 in 10 or even less often) it fails. When it fails than the text is only partially encrypted: This is the error message when it happens: Warning: openssl_decrypt (): IV passed is only 10 bytes long, cipher expects an IV of precisely 16 bytes, padding with. In cryptography, an initialization vector or starting variable (SV) is an input to a cryptographic primitive being used to provide the initial state.
