OpenSSL compatibility

Crypter encrypted strings can be easily decrypted with OpenSSL lib from a CLI. Each encrypted result has a 16 chars long HEX salt and a 32 chars long vector prepended, used as openssl enc params. Break the encrypted output in 3 parts and use them as CLI params:

encrypted string = SALT (16 chars) + VECTOR (32 chars) + ENCRYPTED TEXT (rest of chars left as Base64)

i.e.: 4b7049346438556e + c24f02faba048a44ed81b771562ab01a + U2FsdGVkX19LcEk0ZDhVbg4uYPOo/g0aA2DaNTHQizc=

Encrypt from CLI:

echo -n "my secret text" | openssl enc -e -base64 -A -aes-256-cbc -md sha512 -pbkdf2 -iter 200000 -iv c24f02faba048a44ed81b771562ab01a -S 4b7049346438556e -k mysecretpass

Decrypt from CLI:

echo -n "U2FsdGVkX19LcEk0ZDhVbg4uYPOo/g0aA2DaNTHQizc=" | openssl enc -d -base64 -A -aes-256-cbc -md sha512 -pbkdf2 -iter 200000 -iv c24f02faba048a44ed81b771562ab01a -S 4b7049346438556e -k mysecretpass
