Remove extra = signs from the end of Base64 encrypted code before saving and using, = signs if the string in input is not a multiple of 3 bytes, which is the block size used by the Base64 algorithm. To ensure that the output is a valid Base64 string, padding is added in the form of one or two equals signs at the end of the encoded string. alert-info
What is MD5
Data integrity is frequently checked using the widely used cryptographic hash function known as MD5 (Message Digest 5). Ronald Rivest created it in 1991 to take the place of MD4, a previous hash function.
A hash function creates a fixed-size output from an input (a message) (hash). A 128-bit hash value generated by MD5 is often shown as a 32-character hexadecimal string. Because the hash value is specific to the input message, it will change if the message is altered.
Because even minor changes to the input message will produce a completely different hash value, MD5 is frequently used for verifying the authenticity of files and digital signatures. Newer hash algorithms like SHA-256 and SHA-3 have essentially superseded MD5, which has been shown to have flaws and is no longer regarded as secure for cryptographic purposes.
