    Base62x: An alternative approach to Base64 for only-alphanumeric characters in output.
    Base62x is an non-symbolic Base64 encoding scheme. It can be used safely in computer file systems, programming languages for data exchange, internet communication systems, and is an ideal substitute and successor of many variants of Base64 encoding scheme.<\/p>\n
