Base64#strict_encode64

strict_encode64(bin)

# File tmp/rubies/ruby-3.3.0/lib/base64.rb, line 273
def strict_encode64(bin)
  [bin].pack("m0")
end

Returns a string containing the RFC-2045-compliant Base64-encoding of bin.

Per RFC 2045, the returned string may contain the URL-unsafe characters + or /; see Encoding Character Set above:

Example

Base64.strict_encode64("\xFB\xEF\xBE") # => "++++\n"
Base64.strict_encode64("\xFF\xFF\xFF") # => "////\n"

The returned string may include padding; see Padding above.

Example

Base64.strict_encode64('*') # => "Kg==\n"

The returned string will have no newline characters, regardless of its length; see Newlines above:

Example

Base64.strict_encode64('*') # => "Kg=="
Base64.strict_encode64('*' * 46)
# => "KioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKioqKg=="

The string to be encoded may itself contain newlines, which will be encoded as ordinary Base64:

Example

Base64.strict_encode64("\n\n\n") # => "CgoK"
s = "This is line 1\nThis is line 2\n"
Base64.strict_encode64(s) # => "VGhpcyBpcyBsaW5lIDEKVGhpcyBpcyBsaW5lIDIK"
