A personal identification number (PIN; sometimes redundantly a PIN code or PIN number) is a numeric (sometimes alpha-numeric) passcode used in the process of authenticating a user accessing a system. The PIN has been the key to facilitating the private data exchange between different data-processing centers in computer networks for financial ...
The PIN block is constructed by XOR-ing two 64-bit fields: the plain text PIN field and the account number field, both of which comprise 16 four-bit nibbles. The plain text PIN field is: one nibble with the value of 0, which identifies this as a format 0 block; one nibble encoding the length N of the PIN; N nibbles, each encoding one PIN digit
A six-bit character code is a character encoding designed for use on computers with word lengths a multiple of 6. Six bits can only encode 64 distinct characters, so these codes generally include only the upper-case letters, the numerals, some punctuation characters, and sometimes control characters.
No one should ever ask you for a six-digit verification code — not a stranger on social media, not tech support, not even your bank. If someone does, end the conversation and block their number ...

This means that the first hexadecimal digit in the third group always starts with a 4 in UUIDv4s. Visually, this looks like this xxxxxxxx-xxxx-Mxxx-Nxxx-xxxxxxxxxxxx, where M is the UUID version field. The upper two or three bits of digit N encode the variant. Values are 8, 9, A or B for the 2 bit indication, values C or D for the 3
Because Base64 is a six-bit encoding, and because the decoded values are divided into 8-bit octets, every four characters of Base64-encoded text (4 sextets = 4 × 6 = 24 bits) represents three octets of unencoded text or data (3 octets = 3 × 8 = 24 bits). This means that when the length of the unencoded input is not a multiple of three, the ...
