Password Cipher is a free and open source, small software to help encipher and decipher your password based on a simple algorithm.
You must have all the passwords are the ASCII codes in the range of 0-9, A-Z, and a-z. Then we need to have a master key, also known as cipher key. The cipher key should also in the range of 0-9, A-Z, and a-z.
Then, each character will be given a value, from 0 to 61. The values 0-9 are given to the character 0-9, 10-35 are given to A-Z, and 36-61 are given to a-z.
The cipher key will be repeated to the length of the password.
For example, if the cipher key is “12”, and the password is “abcde”, then the cipher key will be lengthen to “12121”. Noted that, if the cipher key is “0” or “0000…”, the result will be the same.
