How can I extract only the hash digits in the quotations in various strings such as:

```
[file:hashes.'MD5' = '547334e75ed7d4eea2953675b07986b4']

[file:hashes.'SHA1' = '82d29b52e35e7938e7ee610c04ea9daaf5e08e90']

[file:hashes.'SHA256' = 'ff3b45ecfbbdb780b48b4c829d2b6078d8f7673d823bedbd6321699770fa3f84']

```

I need to extract the digits and insert into a table using this script:

```
if item['hash'][:12]=='[file:hashes':    #it finds the hash string from Json dic like above lists
     if item['hash'][22:-2] not in hash_column:    #extracts the digits but only for MD5
          insert_hash_table(item['hash'][22:-2])   #insert the hash digit

```

So in the above example if the strings before the '=' changes due to different hashes then I won't be able to be consistent with my piece of code. Is there anyway to extract only the digits after '=' inside the quotations for all type of hashes ? - e.g. **82d29b52e35e7938e7ee610c04ea9daaf5e08e90**
