概观

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。

Index

  • func Encode(out io.Writer, b *Block) error

  • func EncodeToMemory(b *Block) []byte

  • type Block

  • func Decode(data []byte) (p *Block, rest []byte)

例子

解码

包文件

pem.go

func Encode

func Encode(out io.Writer, b *Block) error

func EncodeToMemory

func EncodeToMemory(b *Block) []byte

type Block

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

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。
