This constant is designed to change over time as new and stronger algorithms are added to PHP. base64encode ( string string ): string Encodes the given string with base64. They should all output qnR8UCqJggD55PohusaBNviGoOJ67HC6Btry4qXLVZc= given the values of secret and Message. PASSWORDDEFAULT: Use the bcrypt algorithm (default as of PHP 5.5.0).
These are the methods that I use to both encode and decode in my daily work. See the stackOverflow question What is the use of base 64 encoding?īelow are some simplified HMAC SHA 256 solutions. In this article, I will share both a simple and a slightly more advanced understanding of Base64 encoding.
Those signatures then needed to be converted to base64. Amazon S3 uses base64 strings for their hashes. There are some good reasons to use base64 encoding. The base64encode () function is an inbuilt function in PHP which is used to Encodes data with MIME base64. MIME additionally enforces a line length of 76 characters plus. Bcrypt is a great choice for hashing passwords because its work factor is adjustable, which means that the time it takes to generate a hash can be increased. Reading the input file in chunks that are a multiple of three bytes in length results in a chunk that can be encoded independently of the rest of the input file. Base64-encoded data takes about 33 more space than the original data. This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies. The API required signing every REST request with HMAC SHA256 signatures. , base64encode(packN4, mtrand(), mtrand(), mtrand(), mtrand()))), 0, 22). Base64 encoding converts triples of eight-bit symbols into quadruples of six-bit symbols. , base64encode(packN4, mtrand(), mtrand(), mtrand(), mtrand()))), 0, 22). base64encode ( string string ): string Encodes the given string with base64. Because this is the only function allow you to decode encoded content. If some one is having little knowledge in php, he can easily hack if I directly encode string. See the stackOverflow question What is the use of base 64 encoding Below are some simplified HMAC SHA 256 solutions. There are some good reasons to use base64 encoding. Amazon S3 uses base64 strings for their hashes. Those signatures then needed to be converted to base64. I recently went through the processing of creating SDKs for an in house API. Simple and convenient Base64 encoding and decoding for PHP - GitHub - delight-im/PHP-Base64: Simple and convenient Base64 encoding and decoding for PHP. 2 How can I encode string using PHP Base64encode function with passing some Salt String I dont want others to hack my string. The API required signing every REST request with HMAC SHA256 signatures. That being said your algorithm looks overly complex to me.Examples of creating base64 hashes using HMAC SHA256 in different languages
Php salt and base64 encoding generator#
If it would be required to be perfectly random you would have to use a secure random number generator like openssl_random_pseudo_bytes.
Php salt and base64 encoding password#
It is not necessary for a salt to be perfectly random, it just should be unique for every password you save to defeat rainbow tables and and cracking several passwords at the same time.
