@SrishtiKishore I cannot see any effort you have done so far. Please, edit your question and add sample code. — Scheff's Cat, Mar 16 '17 at 07:20
@Scheff I have made below regex which is fulfilling three conditions : 1,4 and 5. Below is the regex: ^(?=(.*[a-z]){1,})(?=(.*[\d]){1,})(?=(.*[\W]){0,})(?!.*\s).{4,}$. m looking for below regex: Sequential numbers are not allowed All characters cannot be the same — Srishti Kishore, Mar 16 '17 at 09:55

@SrishtiKishore I played with this for a while based on your and @AfzalPatel s efforts. All I got is this pattern for digits I used to match 2. requirement: `(0|(?<!0)1|(?<!1)2|(?<!2)3|(?<!3)4|(?<!4)5|(?<!5)6|(?<!6)7|(?<!7)8|(?<!8)9|9)`. I struggled trying to combine this with the 3. and 4. requirement. — Scheff's Cat, Mar 19 '17 at 06:33

I guess you want this:

^(?=.*?[a-zA-Z\d])[\w@#&*+=-]+$

I tried with this. This is fulfilling some conditions not all: ^(?=.*?[A-Z])(?=(.*[a-z]){1,})(?=(.*[\d]){1,})(?=(.*[\W]){1,})(?!.*\s).{8,}$ – Srishti Kishore Mar 16 '17 at 07:02
check demo and make pattern as your condition – Afzal Patel Mar 16 '17 at 07:05
