Fscanf in Go
by GoDoc Go os.Stderr fmt.Println fmt fmt.Fprintf fmt.Fscanf
Fscanf scans text read from r, storing successive space-separated values into successive arguments as determined by the format. It returns the number of items successfully parsed. Newlines in the input must match newlines in the format.
Fprintln in Go
by GoDoc Go os.Stderr fmt fmt.Fprintf fmt.Fprintln fmt.Println
Fprintln formats using the default formats for its operands and writes to w. Spaces are always added between operands and a newline is appended. It returns the number of bytes written and any write error encountered.
Fprintf in Go
by GoDoc Go os.Stderr fmt.Fprintf fmt fmt.Printf os
Fprintf formats according to a format specifier and writes to w. It returns the number of bytes written and any write error encountered.
Fprint in Go
by GoDoc Go os.Stderr fmt fmt.Fprint fmt.Fprintf fmt.Print
Fprint formats using the default formats for its operands and writes to w. Spaces are added between operands when neither is a string. It returns the number of bytes written and any write error encountered.
VerifyPKCS1v15 in Go
by GoDoc Go os.Stderr crypto crypto.SHA256 crypto/sha256 encoding/hex
VerifyPKCS1v15 verifies an RSA PKCS#1 v1.5 signature. hashed is the result of hashing the input message using the given hash function and sig is the signature. A valid signature is indicated by returning a nil error. If hash is zero then hashed is used directly. This isn't advisable except for inter...
SignPKCS1v15 in Go
by GoDoc Go os.Stderr crypto crypto.SHA256 crypto/rand crypto/sha256
SignPKCS1v15 calculates the signature of hashed using RSASSA-PKCS1-V1_5-SIGN from RSA PKCS#1 v1.5. Note that hashed must be the result of hashing the input message using the given hash function. If hash is zero, hashed is signed directly. This isn't advisable except for interoperability.
EncryptOAEP in Go
by GoDoc Go os.Stderr crypto/rand crypto/sha256 fmt fmt.Fprintf
EncryptOAEP encrypts the given message with RSA-OAEP.
DecryptPKCS1v15SessionKey in Go
by GoDoc Go os.Stderr fmt.Fprintf hex.DecodeString aes.NewCipher cipher.NewGCM
DecryptPKCS1v15SessionKey decrypts a session key using RSA and the padding scheme from PKCS#1 v1.5. If rand != nil, it uses RSA blinding to avoid timing side-channel attacks. It returns an error if the ciphertext is the wrong length or if the ciphertext is greater than the public modulus. Otherwise,...
DecryptOAEP in Go
by GoDoc Go os.Stderr crypto/rand crypto/sha256 encoding/hex fmt
DecryptOAEP decrypts ciphertext using RSA-OAEP.
Scanner.Bytes in Go
by GoDoc Go os.Stderr bufio bufio.NewScanner fmt fmt.Fprintln
Return the most recent call to Scan as a []byte.
Scanner (Words) in Go
by GoDoc Go os.Stderr bufio bufio.NewScanner bufio.ScanWords fmt
Use a Scanner to implement a simple word-count utility by scanning the input as a sequence of space-delimited tokens.
Scanner (Lines) in Go
by GoDoc Go os.Stderr bufio bufio.NewScanner fmt fmt.Fprintln
The simplest use of a Scanner, to read standard input as a set of lines.
Scanner (EmptyFinalToken) in Go
by GoDoc Go os.Stderr bufio bufio.ErrFinalToken bufio.NewScanner fmt
Use a Scanner with a custom split function to parse a comma-separated list with an empty final value.
Stdin Line Filter in Go
by yhuang Go os.Stderr bufio bufio.NewScanner fmt fmt.Fprintln
Here’s an example line filter in Go that writes a capitalized version of all input text. You can use this pattern to write your own Go line filters.
String Formatting in Go
by yhuang Go os.Stderr fmt.Printf fmt fmt.Fprintf fmt.Println
Go offers excellent support for string formatting in the printf tradition. Here are some examples of common string formatting tasks.
Go's defer
by yhuang Go os.Stderr fmt.Println os.File fmt fmt.Fprintf
Defer is used to ensure that a function call is performed later in a program’s execution, usually for purposes of cleanup. defer is often used where e.g. ensure and finally would be used in other languages.
