This ensures that the data remains intact without modification during transport. When the term "Base64" is used on its own to refer to a specific algorithm, it typically refers to the version of Base64 outlined in RFC 4648, section 4, which uses the following alphabet to represent the radix-64 digits, alongside = as a padding character: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/Ī common variant is "Base64 URL safe", which omits the padding and replaces +/ with -_ to avoid characters that might cause problems in URL path segments or query parameters.īase64 encoding schemes are commonly used to encode binary data for storage or transfer over media that can only deal with ASCII text (or some superset of ASCII that still falls short of accepting arbitrary binary data). The term Base64 originates from a specific MIME content transfer encoding. SMPTE (Society of Motion Picture and Television Engineers)īase64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation.RTP (Real-time Transport Protocol) and SRTP (Secure RTP).Rule 2: That rule is also known as leading zero compression. According to that rule, if an IPv6 address contains continuous zeros, then they are replaced with (::). Rule 1: That rule is also called the zero compression rule. DTMF (Dual-Tone Multi-Frequency signaling) The rules to compress the IPv6 address are followed.DTLS (Datagram Transport Layer Security).
