Generate Base64 MD5 SHA1 of any string

Online Encoder generates MD5, Base64, & SHA1 encryption of any string, text, or password. Just enter any text or string and instantly convert it into MD5, Base64, & SHA1 encrypted form.

What is a Hash function?

Many applications or technologies use that technique to avoid security breaches and for faster search results.

Hashing is a cryptographic function that takes an input of variable length and returns a fixed-size alphanumeric string. The string is called the hash value, message digest, digital fingerprint, digest, or checksum.

Fundamentals of Hashing

• The Hash functions are one-way. We cannot reverse a hash value to recover the original content, which is irreversible.
• Moving the same content through the same hash function should produce the same output or hash value. That means the hash functions' output is of fixed length and can alter depending upon the hash function you use, but the hash's length would not change for a specific hash function.

So, there are two required rules that each hash function must follow.

1. The original content should not be derivable from the hash value or message digest.
2. The two different contents cannot have the same message digest.

Use cases of Hashing

• Generate passwords to store them for later use in authentication of users in databases
• To keep the credit card numbers and other essential data in databases
• In creating digital signatures and message verification codes
• Indexing data in hash tables
• Detecting copied data
• For fingerprinting
• To sort and identify files to ensure the data integrity of the files
• Act as checksums in detecting accidental data corruption

SHA1 Hash

SHA stands for Secure Hashing Algorithm. SHA1 hash is an algorithm used to generate the 160 bits hash value.

SHA is generated by breaking our input content into "n'' number of parts that we represent as X, each of 448 bits, and add 64 bits of padding to each, converting their total length to 512 bits. These 512 bits are then brought in the compression function along with the 160 bits of compressed output. We have a pre-set value for the 160 bits for the first time we carry this out.

That process continues for "n" times until the last 160 bit of the message is produced.

Undoubtedly, the SHA1 algorithm is complex, but the significant part is that it is not used anymore because it has been cracked and is considered unsafe.

MD5 Hash

MD5 stands for Message-Digest Algorithm 5. Ronald Rivest invented that cryptographic function in 1991.

The primary function of MD5 is to calculate the hash value in cryptography. It takes the block of data as input and returns the fixed-size bit string as a hash value.

MD5 is also a hash algorithm, which means it follows the same rules as the hash algorithm. It takes the data of any size as input and gives you a fixed size 128 bits (16 bytes) output.

MD5 is irreversible. Suppose we use the MD5 algorithm on text data of about 750,000 characters. But the final output is of 32 digits digest. So, how can we ensure the accuracy at which the 32 digits digest be converted to 750,000 characters? That's the reason MD5 does not have a reversible function.

The drawback is that MD5 is already cracked, and it is recommended not to use it with sensitive data like banking or e-commerce.

Base64 Encoding

By words, encoding is the process of converting any text into some particular form. Base64 is a binary to ASCII encoding scheme that stores and transfers the binary data over medium, supporting only textual data. The encoding scheme uses the 64 characters set that are present in the majority of the character sets.

In Base64, the data are broken down into 24 bits (three bytes). These three bytes (24 bits) are further broken down into four packs of six bits each. These 6 bits reveal the character supported by the characters set in the base 64 scheme.

Unlike MD5 and SHA1, you can decode the Base64 encoded text and decode the image from the Base64 encoded string.

How to use the online encoder to generate Base64, MD5, and SHA1 encrypted form of a string?

To generate the Base64, MD5, SHA1 of a string, perform the following steps.

• Open the Online Encoder - Base64, MD5, and SHA1 Generator.
• Enter any string, text, or password in the space provided for that section, and click on the "Generate" button.
• The tool gives you the Base64, MD5, and SHA1 encrypted form of the provided text.
