Is there a standard for determining if a secret key / hash is secure?

What is the basis for a certain algorithm being declared secure/broken?
Is there a standard like below?
*I understand that there are certain unique flaws such as collisions based on which algorithm is used.

time to compute single = T
conditions = C
number of possibilities = N
Min time required = M

Given C: T * N > M

Are there any possible methods for us identifying byte sequences which contains some plaintext? [on hold]

I want to implement one algorithm for automatically identifying some plaintext info from byte sequences. For example:

6d 6c 70 00 00 00 01 d0 03 05 00 00 00 00 00 00 mlp….. ……..
27 14 00 00 00 00 01 a7 e5 1a 00 2c 62 7… Continue reading Are there any possible methods for us identifying byte sequences which contains some plaintext? [on hold]
