# Can the xor of two RNG outputs ever be less secure than one of them?

 HOME ยป Information Security
Suppose I'm suspicious that one or more (pseudo)-random number
generators is cryptographically flawed, perhaps even deliberately
backdoored. The RNGs in this case might be either PRNG algorithms,
hardware random number generators, or some OS-provided primitive whose
source might be either of these.Can it ever be a bad thing to "salt"
the RNG by using the xor of its output and some other RNG's output?
The latter RNG might be of much lower quality but be unlikely to have
been compromised by th
 How to do in python e.g. enc_price = pad price I am new to crypto and I am trying to interpret the below code. Namely, what does `` mean?I have a secret_key secret key. I also have a unique_id. I create pad using the below code. ```pad = hmac.new(secret_key, msg=unique_id, digestmod=hashlib.sha1).digest()``` />Once the pad is created, I have a price e.g. 1000. I am trying to follow this instruction which is pseudocode:```enc_price = pad price```In Python, what is the code to implement `enc_price = pad price`? What is the logic behind doing this? Programming Languages after XOR operation find C (and XOR reversability) Assume:```unsigned char A = 10;unsigned char B = 11;unsigned char C = 12;unsigned char Diff1 = A ^ B; />unsigned char Diff2 = B ^ C;//find any of A or B or C using Diff1 and Diff2```Question is: There were 3 values initially for which we found 2 differences. Is there any way we can find any of A or B or C using 2 differences Diff1 and Diff2? />I know XOR is not reversible unless you know the key, but keeping in view that unsigned __int8 is 0...255 maximum 256 different values.stay well. Programming Languages Would CSPRNG + XOR be a secure encryption method? Similarily to RC4 (RC4_PRNG+XOR ), would it be secure to use another CSPRNG(Cryptographically secure pseudorandom number generator)[Isaac, BlumBlumShub, etc) instead of RC4's and XOR the data with the resulting keystream? Development Tools & Services C script for table outputs correctly and then outputs default case. how to fix? What am I doing wrong? If I press M, A, or P, it will ask me for what size table. Then it outputs the table correctly, and then outputs "not a choice....".

It is possible for x to have more than one output, y. For example: x1,y11,y12,y13,...,y1n x2,y21 x3,y31,y32 ...And I would like to manipulate the data so that it looks like: x1,y11 x1,y12 x1,y13 ... x1,y1n x2,y21 x3,y31 x3,y32 ...I'm attempting to do this with sed.
