Base64. In computer programming, Base64 is a group of binary-to-text encoding schemes that transforms binary data into a sequence of printable characters, limited to a set of 64 unique characters. More specifically, the source binary data is taken 6 bits at a time, then this group of 6 bits is mapped to one of 64 unique characters.
The name "uuencoding" is derived from Unix-to-Unix Copy, i.e. "Unix-to-Unix encoding" is a safe encoding for the transfer of arbitrary files from one Unix system to another Unix system but without guarantee that the intervening links would all be Unix systems. Since an email message might be forwarded through or to computers with different ...
Quoted-Printable, or QP encoding, is a binary-to-text encoding system using printable ASCII characters ( alphanumeric and the equals sign =) to transmit 8-bit data over a 7-bit data path or, generally, over a medium which is not 8-bit clean. Historically, because of the wide range of systems and protocols that could be used to transfer messages ...
In the context of an HTTP transaction, basic access authentication is a method for an HTTP user agent (e.g. a web browser) to provide a user name and password when making a request. In basic HTTP authentication, a request contains a header field in the form of Authorization: Basic <credentials>, where <credentials> is the Base64 encoding of ID ...
base64: Encodes or decodes Base64, and prints result to standard output cat: Concatenates and prints files on the standard output cksum: Checksums (IEEE Ethernet CRC-32) and count the bytes in a file. Supersedes other *sum utilities with -a option from version 9.0. comm: Compares two sorted files line by line csplit
The bcrypt function uses these inputs to compute a 24-byte (192-bit) hash. The final output of the bcrypt function is a string of the form: $2<a/b/x/y>$ [cost]$ [22 character salt] [31 character hash] For example, with input password abc123xyz, cost 12, and a random salt, the output of bcrypt is the string.
iconv. In Unix and Unix-like operating systems, iconv (an abbreviation of internationalization conversion) [2] is a command-line program [3] and a standardized application programming interface (API) [4] used to convert between different character encodings. "It can convert from any of these encodings to any other, through Unicode conversion."
PKCS 8. In cryptography, PKCS #8 is a standard syntax for storing private key information. PKCS #8 is one of the family of standards called Public-Key Cryptography Standards (PKCS) created by RSA Laboratories. The latest version, 1.2, is available as RFC 5208.
