Description: Stream cipher and eStream winner.
Uses: Performance is very impportant.
Key size: from 128 to 256 bits, guaranteed security is only 128 bits.
Iv size: 128 bits
Description: Stream cipher and eStream winner.
Uses: Performance is very impportant.
Key size: varibale
Iv size: 64 bits

stream(data_js)
In this example we encrypt and decrypt Hello world! string with the key and iv given
On data_js["algorithm"] can be SOSEMANUK or SALSA20
Json to enc string (key and iv depends on algorithm you chose)
{"algorithm":"estream flavor","plaintext":"your string","hex": BOOL,"iv":"Hex stringsize=16,32",
"version":1,"key":"Hex stringsize=32-64","operation":"enc","type":"string"}
Json to dec string (key and iv depends on algorithm you chose)
{"algorithm":"estream flavor","plaintext":"your hex enc string ","iv":"Hex stringsize=16,32",
"version":1,"key":"Hex stringsize=32-64","operation":"dec","type":"string"}
Json to enc file (key and iv depends on algorithm you chose)
{"algorithm":"estream flavor","file":"your file","iv":"Hex stringsize=16,32",
"version":1,"key":"Hex stringsize=32-64","operation":"enc","type":"file"}
Json to dec file (key and iv depends on algorithm you chose)
{"algorithm":"estream flavor","file":"your file","iv":"Hex stringsize=16,32",
"version":1,"key":"Hex stringsize=32-64","operation":"dec","type":"file"}
