base64 decode Online

Base 64 is binary to text encoding and decoding process. It simply represents binary data in ASCII or ASCII to binary format. It can be used to carry data in binary formats.

It can also use to embed files or any other binary assets in HTML or CSS files. It is used in sending an email attachment. It is used in SMTP format. It transports 7-bit ASCII characters.

The base 64 represents 64 digit values which are varied with digit values. The strategy is to select characters that are common in many encodings. It is used in the transmission of modified information. It can be used in distributed computing. There are many base64 decode online portals.

Base 64 is a six-bit encoding that is decoded in values of 8 bits for modern computers. Here every four bits three octets. It has the length of encoded input that must have padding added for its layer of multiple of four.

Here padding character is = it means there is no need for further bits to execute codes. The padding is not very essential for decoding but the number of missing bytes can be inferred with the length of encoded text. Sometimes padding is very mandatory. In the decoding process, four characters are converted into three bytes.

Without padding, the decoding to three bytes is done over and over again. There are fewer encoded codes that remain.

Advantages of Base64:

  • Privacy Enhancing Email: It has standardized use in encoding. It is called MIME. It follows the privacy-enhanced electronic protocol. PEM defines the printable encoding that can transform to an arbitrary sequence of octets. It is used in SMTP protocol. To convert into a PEM encoding the first byte is most significant in the 24 bits. If there are fewer than three bits then the buffer bits will be zero. You can take the service of base64 decode online.
  • MIME: It is an extension of base 64 as one of the binary to the text encoding scheme. It is based on RFC 1421 version. It does not specify the field length for the base 64 encoded line.
  • UTF7: It was also known as RFC1642. These schemes utf 16 as ASCII characters are used to transfer the 7-bit transport. The modified based base 64 alphabet is the MIME 64 alphabet. It does not use padding characters. Base 64 modified versions omit the padding and end immediately.
  • Open PGP: It is radix encoding and is also called ASCII armor. The checksum is calculated on the data before encoding.
  • RFC 3548: It attempts the unification of RFC1421 and RFC 2045 for the base 64 encodings. It is alternative alphabet encodings.

It can be helpful in fairly lengthy identifying information in the HTTP environment. Its database is formed with java that uses it to decode and encode large unique id in the string case. It decodes and encodes binary data and is convenient in the usage of URLs. It is used to render encoding and decoding a compact way.

It has usage in Html function with javascript methods. It can be used in decoding and encoding the webpage.
