First, you know what to do with md5. You can refer to google's article: http://segmentfault.com/blog/liangyi/1190000002409125
In general, md5 is an information digest algorithm, which is irrelevant to a specific language. You can use java, php, or javascript. the md5 value is changed based on whether the information is changed. For the same piece of information, the values calculated in the above language should be the same. Different means they have different implementations of algorithms.
The md5 of js is implemented by a third party.
After all, since it is called md5, the algorithm must be the same, but it is nothing more than the returned data value type.May
Differences
The md5 calculation result is a-bit hash value. Some Java libraries return a 16-Byte array (8bit = 1 Byte ), most of the standard md5 implementations directly return the Hex representation of these 16 bytes, that is, a string consisting of 32 hexadecimal numbers.
