php - mysql check data in sha512 encryption -


i need check data in sha512 encryption mysql query , php

i can md5 :

select * text md5(id) = '$id'

but , how in sha512?

regards

mysql 5.5+

select * text sha2(id, 512) =  '$id'

more details :

sha2(str, hash_length)

calculates sha-2 family of hash functions (sha-224, sha-256, sha-384, , sha-512). first argument cleartext string hashed. second argument indicates desired bit length of result, must have value of 224, 256, 384, 512, or 0 (which equivalent 256). if either argument null or hash length not 1 of permitted values, return value null. otherwise, function result hash value containing desired number of bits. see notes @ beginning of section storing hash values efficiently.

the return value nonbinary string in connection character set.

mysql> select sha2('abc', 224);         -> '23097d223405d8228642a477bda255b32aadbce4bda0b3f7e36c9da7'

this function works if mysql has been configured ssl support. see section 6.3.9, “using ssl secure connections”.

sha2() can considered cryptographically more secure md5() or sha1().

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
