fn decode(data string) ?(Block, string)

decode reads data and returns the first parsed PEM Block along with the rest of the string. none is returned when a header is expected, but not present or when a start of '-----BEGIN' or end of '-----END' can't be found in data

fn new(block_type string) Block

returns a new Block with the specified block_type

enum Header {
	proctype
	contentdomain
	dekinfo
	origid_asymm
	origid_symm
	recipid_asymm
	recipid_symm
	cert
	issuercert
	micinfo
	keyinfo
	crl
}

Headers as described in RFC 1421 Section 9

fn (header Header) str() string

str returns the string representation of the header

struct Block {
pub mut:
// from preamble
	block_type string
// optional headers
	headers map[string][]string
// decoded contents
	data []u8
}

fn (block Block) encode(config EncodeConfig) !string

encode_config encodes the given block into a string using the EncodeConfig. It returns an error if block_type is undefined or if a value in headers contains an invalid character ':'

default EncodeConfig values wrap lines at 64 bytes and use '\n' for newlines

fn (mut block Block) free()

free the resources taken by the Block block

fn (block Block) header_by_key(key Header) []string

returns the selected key using the Header enum

same as block.headers[key.str()]

struct EncodeConfig {
pub mut:
// inner text wrap around
	line_length int = 64
// line ending (alternatively '\r\n')
	line_ending string = '\n'
}
