import "encoding/pem"
Overview
Index
Examples
Package pem实现了PEM数据编码,该编码源于Privacy Enhanced Mail。目前最常见的PEM编码用在TLS密钥和证书中。请参阅RFC 1421。
func Encode(out io.Writer, b *Block) error
func EncodeToMemory(b *Block) []byte
type Block
func Decode(data []byte) (p *Block, rest []byte)
解码
pem.go
func Encode(out io.Writer, b *Block) error
func EncodeToMemory(b *Block) []byte
块表示PEM编码结构。
编码形式是:
-----BEGIN Type-----Headers base64-encoded Bytes-----END Type-----
其中标题是一个可能为空的Key:Value行的序列。
type Block struct { Type string // The type, taken from the preamble (i.e. "RSA PRIVATE KEY"). Headers map[string]string // Optional headers. Bytes []byte // The decoded bytes of the contents. Typically a DER encoded ASN.1 structure.}
func Decode(data []byte) (p *Block, rest []byte)
解码将在输入中找到下一个PEM格式化的块(证书,私钥等)。它返回该块和输入的其余部分。如果没有找到PEM数据,则p为零,并且整个输入在休息时返回。
