Question on Encryption

I inherited a table that has a column that holds passwords. I never dealt with this before. My questions are:
How could I insert a new record with a password in here?
How would I be able to update a password for an existing one?
Is there a way to see the existiing ones?

Thank you

If they are encrypted you must decrypt to see them and encrypt the updated or new passwords for insert.

thanks but how would you do that?

How is the password column encrypted?

Hi, I am sorry I have no information I just inherited the table. Is there a standard process for decrypting, updating the column?

You need to know how it is encrypted and the key.

Unless it was done properly and they are only storing the hash - which cannot be decrypted.

thank you
